[Bug 1890435] Re: gcc-10 breaks on armhf (flaky): internal compiler error: Segmentation fault

[Christian Ehrhardt ]

Ok, apport through the stack of LXD is ... not working.
I have used a more mundane core pattern and a C test program to ensure I will get crash dumps.

$ cat /proc/sys/kernel/core_pattern
/var/crash/core.%e.%p.%h.%t

$ gcc test.c ; ./a.out ; ll /var/crash/
Segmentation fault (core dumped)

Trying to run into the real gcc crash again with this ensured ...

Title:
  gcc-10 breaks on armhf (flaky): internal compiler error: Segmentation
  fault

Status in gcc-10 package in Ubuntu:
  New

Bug description:
  Hi,
  this could be the same as bug 1887557 but as I don't have enough data I'm filing it as individual issue for now.

  I have only seen this happening on armhf so far.
  In 2 of 5 groovy builds of qemu 5.0 this week I have hit the issue, but it is flaky.

  Flakyness:
  1. different file
  first occurrence
  /<<PKGBUILDDIR>>/target/s390x/excp_helper.c:544:1: internal compiler error: Segmentation fault
  second occurrence
  /<<PKGBUILDDIR>>/linux-user/syscall.c:12479:1: internal compiler error: Segmentation fault

  Being so unreliable I can't provide mcuh more yet.
  I filed it mostly for awareness and so that I can be dup'ed onto the right but if there is a better one.
