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

[Christian Ehrhardt ]

There is a new gcc-10 version from two days ago in groovy now.
I was talking with doko and we wanted to try different gcc-10 versions in general trying to corner the issue to when it started to appear.

https://launchpad.net/ubuntu/+source/gcc-10/10.1.0-6ubuntu1 - WIP
https://launchpad.net/ubuntu/+source/gcc-10/10.2.0-9ubuntu2 - fails
https://launchpad.net/ubuntu/+source/gcc-10/10.2.0-11ubuntu1 - WIP

I usually had the crash in 1-2 runs, so I will consider 4 good runs as
the issue being not present. Although there is some racyness to this I
just can't wait much longer without growing out of a day for a single
test :-/

I'll update once the I got more results

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.
