hey there :3
i went to deploy to a pretty wonky debian server yesterday but the compiler segfauted. at this point we are sure that this is triggered by the system being misconfigured in some way. we also found issues with memory slots however after having roughly tested the ram with memtest we still ran into the same segfaults. the compiler segfaults disappeared once we booted a different system on the hardware (this is to say that there might be hardware issues involved but imo rather unlikely and more likely this by frankensteinish system configs {however one thing to note is that the rest of the services on that server are seemingly healthy since quite a while}).
i hope all of this is put concretely enough, if anything is missing please let me know and i can provide more information. we do have backups of this system, but are planning to do a clean install on friday after which i don't know if i am realistically going to be able to reproduce this behavior.
a basic hello world segfaulted more often then not (but it might also compile).
so this:
cargo new hello_world && cd hello_world
# we made sure to always rebuild from scratch as otherwise one passing build would
# make all subsequent builds fail
cargo build && rm -rf target Meta
rustc --version --verbose:
rustc 1.76.0 (07dca489a 2024-02-04)
binary: rustc
commit-hash: 07dca489ac2d933c78d3c5158e3f43beefeb02ce
commit-date: 2024-02-04

release: 1.76.0
LLVM version: 17.0.6
i also tried nightly but also ran into segfaults there.
uname -a
Linux hostname 4.19.0-25-amd64 #1 SMP Debian 4.19.289-2 (2023-08-08) x86_64 GNU/Linux
and
Linux hostname 5.10.0-28-amd64 #1 SMP Debian 5.10.209-2 (2024-01-31) x86_64 GNU/Linux
(i upgraded the system to no avail - one thing of note may be that i specifically could not find any reference to the syscall futex_waitv which is 5.19 and later but only futex_wait)
apt list libc6-dev (as syscalls and futex timeouts were involved)
libc6-dev/oldstable,now 2.31-13+deb11u8 amd64 (installed)
and
apt list libc6
libc6/oldstable,now 2.31-13+deb11u8 amd64 (installed)
(and i also installed all recommended or suggested libc on pacakges.debian)
Error output
i have quite a few more error logs and i think that the segfaults didnt always happen in the same ways.

i also found panics in raw vec because of capacity overflows (there are even more traces where i think the causes are different, i am happy to provide them and can also go through them on another day {right now i just need to go to bed 😬})
