I know this bug doesn't forllow the template, I'll try to be as precise as possible, but I can't reproduce systematically the problem...
I've created a really big project, almost made completely of serde proc-macros, you can find it here: https://github.com/nappa85/serde_fix/
As soon as the project started getting bigger, the builds started failing, I've split it in a workspace, but I haven't solved completely the problem.

The fails are random, and seems to happen more often on a "dirty" environment, where with "dirty" I mean without calling cargo clean before.

I noticed the failure rate is kind of inverse proportional to the number (or the kind) of errors in the code.
For example, before implementing Default for every enum in the code, and therefore having an error for missing Default for every non Option-wrapped enum, it was really hard to get a non failing build.

Now that the code is cleaner, to trigger the failure I created a script that adds a comment to a shared crate and then restarts ¢argo check for all toolchains: https://github.com/nappa85/serde_fix/blob/master/runtest.sh
I run it like I=0; while ./runtest.sh; do :; done

Normally rustc fails with something like:

  process didn't exit successfully: `rustc --crate-name fixt11 --edition=2018 fixt11/src/lib.rs --error-format=json --json=diagnostic-rendered-ansi --crate-type lib --emit=dep-info,metadata -C embed-bitcode=no -C debuginfo=2 -C metadata=045522708ff761af -C extra-filename=-045522708ff761af --out-dir /home/marcon/Progetti/serde_fix/target/debug/deps -C incremental=/home/marcon/Progetti/serde_fix/target/debug/incremental -L dependency=/home/marcon/Progetti/serde_fix/target/debug/deps --extern fix_common=/home/marcon/Progetti/serde_fix/target/debug/deps/libfix_common-b432d750f411466d.rmeta --extern serde=/home/marcon/Progetti/serde_fix/target/debug/deps/libserde-3d4d15af8ef49c31.rmeta --extern serde_fix=/home/marcon/Progetti/serde_fix/target/debug/deps/libserde_fix-798dff9103619a78.rmeta` (signal: 11, SIGSEGV: invalid memory reference)

Sometimes, after a failure, I'm not able to restart a build until I run cargo clean, the build fails with:

memory allocation of 104733814464 bytes failed
Aborted (core dumped)

Only once it failed with a backtrace, that is:

Backtrace

note: the compiler unexpectedly panicked. this is a bug.

note: some of the compiler flags provided by cargo are hidden

My machine is an AMD Ryzen 7 4700U with 16GB of RAM running Kubuntu 21.04 (same problems with 20.04 and 20.10).
If you need any additional info, just ask me, my goal is to help improve the compiler.

@nappa85: How many runs of runtest.sh did it take to reproduce the crash? The project is compiling very slowly for me, and taking large amounts of memory (~4-5 GB)

As I already told, it's completely random.
The core dump I attached happened on first try, for example.
I'm actually using another machine to exclude the hardware problem, at the beginning of the sixth iteration of runtest.sh I had this failure:

  process didn't exit successfully: `rustc --crate-name fix50sp2 --edition=2018 fix50sp2/src/lib.rs --error-format=json --json=diagnostic-rendered-ansi --crate-type lib --emit=dep-info,metadata -C embed-bitcode=no -C debuginfo=2 -C metadata=a28a0a3657aedba2 -C extra-filename=-a28a0a3657aedba2 --out-dir /home/nappa85/temp/target/debug/deps -C incremental=/home/nappa85/temp/target/debug/incremental -L dependency=/home/nappa85/temp/target/debug/deps --extern fix_common=/home/nappa85/temp/target/debug/deps/libfix_common-b432d750f411466d.rmeta --extern fixt11=/home/nappa85/temp/target/debug/deps/libfixt11-045522708ff761af.rmeta --extern serde=/home/nappa85/temp/target/debug/deps/libserde-3d4d15af8ef49c31.rmeta --extern serde_fix=/home/nappa85/temp/target/debug/deps/libserde_fix-798dff9103619a78.rmeta` (signal: 9, SIGKILL: kill)

Seems like a kill for timeout or for memory consumption, but I don't understand why on the 5 previous iterations it was ok...

If it was killed by the linux OOM killer, there should be a message in the kernel log which you can see by running dmesg. This would also explain the randomness, b/c whether you hit it would depend on how much memory all other applications on the system are using.

Just to make sure, the system this was originally reproduced with is running at stock, no memory/CPU overclock? Asking because it is extremely popular to run Ryzen with overclocked memory via XMP or a similar technology and sometimes such overclocks do result in issues like these being reported against this repository.

No overclock at all, it's a brand new notebook

An update on the topic:
I've run my script for more than 12 hours on another machine without a problem, only now it has been killed, but I think it's a load problem.
It must be said that this machine is slower than mine, a full project builds here takes 30 minutes, on my machine it takes only 6 minutes.

I'm stress-testing my machine in every way to exclude an hardware problem, but at the moment without luck.
Memtest86 says the memory is ok, I've tried stress (http://manpages.ubuntu.com/manpages/hirsute/man1/stress.1.html) with stress --cpu 8 --io 8 --vm 20 --vm-bytes 1024M --vm-keep without a single problem...
If you know how to exclude hardware problems, just tell me

I've run RUSTFLAGS='-Z time-passes' cargo +nightly check on the workspace, this is the result:
time_passes.txt

As you can see, there are several point where more than 3GB of RAM is taken, a point takes almost 5GB...
I don't know if it can be considered normal on a crate made only of serde structs...

This looks like an OOM condition to me. The build takes almost 12 GiB of memory here. FWIW, attached is the output of RUSTFLAGS='-Z time-passes' cargo +nightly build 2>&1 | tee time on my machine.

I don't think it's an OOM, the error is randomic like an UB.
I've just replicated the error on windows, on the same hardware, at the fifth build (the first four correct).
On windows it's a bit slower and it doesn't even reach 100% RAM usage

The rust-analyzer panic is unrelated (and just a normal panic).

Since the issue presents itself more reliably over multiple runs of the compiler, you can make a script that runs the a given task N times before declaring a commit to be "good".

Sorry for the long silence, it took me more than 10 days to prove Lenovo support that there were hardware problems even if tests passes. Now with a brand new hardware everything is stable. Closing the issue

I bumped into the same issue today.

My Machine's CPU is: AMD Ryzen 7 5800H with Radeon Graphics
My Machine's host OS is: Ubuntu 23.04
My Machine's guest OS is: alpine 3.17

I build cargo-c via docker, podman, virtualbox, kvm+qemu respectively, all failed due to this. finally, I build it using GitHub Actions: https://github.com/leleliu008/test/actions/runs/4769013342/jobs/8478957739 , it failed too.
