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

[Christian Ehrhardt ]

I got the crash in the repro env.
dmesg holds no OOM which is good - also no other dmesg/journal entry that would be related.

It might be depending on concurrent execution as this was the primary change to last time.
And not having set up apport/whoopsie to catch the crash :-/
I've installed them now and run the formerly breaking command in a loop.

For the sake of "just eating cpu cycles" I have spawned some cpu hogs in the background.
But with all that in place it ran the compile 300 times without a crash :-/

It seems I have to re-run in the build env and hope that apport will
catch it into /var/crash this time :-/

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.
