Description Steve Grubb 2022-01-27 19:54:41 UTC

Description of problem:
While compiling suricata on rawhide i686, rustc is segfaulting.

This is the relevant build log (very bottom):
https://kojipkgs.fedoraproject.org//work/tasks/7972/81987972/build.log

error: could not compile `suricata`
Caused by:
  process didn't exit successfully: `rustc  <snip>  (signal: 11, SIGSEGV: invalid memory reference)


Version-Release number of selected component (if applicable):
rust-1.58.1-1.fc36.i686

How reproducible:
always

Steps to Reproduce:
1. Build suricata for i686

Additional info:
No idea if this is related to gcc12 mass rebuild issues.

They're all within llvm::ScheduleDAGSDNodes::EmitSchedule. I'll see if I can extract LLVM IR and reproduce it with llc directly.

Comment 2 Ben Cotton 2022-02-08 20:27:37 UTC

This bug appears to have been reported against 'rawhide' during the Fedora 36 development cycle.
Changing version to 36.

Comment 3 Josh Stone 2022-08-29 21:03:34 UTC

I can't reproduce this anymore.
