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 | }
