clang crashes while compiling #91166

Open Florikoeln opened 2 months ago

Florikoeln commented 2 months ago

I compiled a file on a new set-up raspberry pi Zero W. The library compiled many times before - even on the same raspberry pi. Please find the output below, the two requested files are attached.; due to security settings I had to change the filename. 

PLEASE submit a bug report to https://github.com/llvm/llvm-project/issues/ and include the crash backtrace, preprocessed source, and associated run script.

fk_tools-548dc2_c.txt fk_tools-548dc2_sh.txt

I hope this time it worked. Please note that our company regulations allow no .c and no .sh-files, therefore I changed the filename to .txt.

I've attempted to reproduce, building on an aarch64 machine under a debian 12 (bookworm) docker container. It's llvm 14.0.6; I wasn't able to get a crash. The reproducer doesn't fire on the main branch (with asserts) for me either.

Can you confirm that running the reproducer script does reproduce the crash for you and that this isn't a transient issue? Under a debian 12 docker container I'm running fk_tools-548dc2.sh and this gives me an object file as output of size 7568 bytes.

(edited to add) My docker image repro bits, running docker run -ti --rm -v $PWD:$PWD -w $PWD debian:

I updated the raspi (sudo apt update / upgrade), and tried again: clang still crashes
