Bug ID: 66368
Summary: [5 Regression] go tool crashes on powerpc-linux-gnu
Product: gcc
Version: 5.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: go
Assignee: ian at airs dot com
Reporter: doko at gcc dot gnu.org
CC: cmang at google dot com
Target Milestone: ---
"go version" on powerpc-linux-gnu works with the 5.1 release candidate, but
crashes with the 5.1.0 release, and the current branch.
reverting the changes made in PR65787 fixes the issue. Seen on Ubuntu 15.04 and
15.10 systems, however I can't reproduce this in Debian unstable. Same binutils
version, Debian has glibc-2.19, Ubuntu glibc-2.21. It looks like I can't
reproduce this with a GCC trunk build on either platform. So I'm a bit lost ...
