            Bug ID: 97368
           Summary: randomly build failure for mesa with lto on armhf
           Product: gcc
           Version: unknown
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: lto
          Assignee: unassigned at gcc dot gnu.org
          Reporter: pedretti.fabio at gmail dot com
                CC: marxin at gcc dot gnu.org
  Target Milestone: ---

When building mesa git (actually on b7d16a) I get randomly build failures on
armhf.
gcc is the one currently on Ubuntu groovy (10.2.0-13ubuntu1).

I don't get this build error with gcc 9, or on other architectures (amd64 arm64
i386 ppc64el s390x) even with the same gcc 10.

This is the actual error:

during RTL pass: reload
../src/compiler/nir/nir_loop_analyze.h: In function ‘contains_other_jump’:
../src/compiler/nir/nir_loop_analyze.h:71:1: internal compiler error:
Segmentation fault
   71 | }
      | ^

>From the error message I suppposed it was an LTO problem, however, even when
disabling LTO I still get the error.
Note the "The bug is not reproducible, so it is likely a hardware or OS
problem." which is part of the log.
Posting here anyway.
