Bug ID: 81763
Summary: Issues with 32bit x86 apps on GCC 7.1+
Product: gcc
Version: 7.1.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c
Assignee: unassigned at gcc dot gnu.org
Reporter: mike at fireburn dot co.uk
Target Milestone: ---
I've been seeing issues with 32bit x86 llvm & mesa when using GCC 7.1.0 and
I've just tested GCC 7.2 RC
When llvm & mesa are compiled with GCC 7.1.0+ and I run a 32bit glxgears it
segfaults, the 64bit version work fine and if I recompile with GCC 6.3.0
everything works fine too (games also segfault but glxgears is a nice cut down
example)
This is only with the radeonsi driver, i965 works fine

It would be nice to rule out a GCC issue before 7.2.0 is released, the last
time I tried turning on debugging the issue no longer manifested.
Is there anything you can think of that might help pinpoint the bug?
