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

[Christian Ehrhardt ]

I've learned that the gcc in hirsute has the checking enabled atm.
That explains why any qemu 5.1 build I do (merging) or Doko's rebuild on [1] fail atm.

New GCC build is coming in [2] that has the fix applied but the checking no more enabled.
Once built I'll re-test that one as well.

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.
