            Bug ID: 103656
           Summary: get_cpuid inline asm violates red zone
           Product: PulseAudio
           Version: unspecified
          Hardware: Other
               URL: https://gcc.gnu.org/bugzilla/show_bug.cgi?id=82926
                OS: All
            Status: NEW
          Severity: normal
          Priority: medium
         Component: core
          Assignee: pulseaudio-bugs at lists.freedesktop.org

            Blocks: 99066

The original issue with get_cpuid() came while trying to debug bug 99066 and
has been forwarded to GCC (see URL above).

Apparently the current implementation of get_cpuid() is violating the red zone
(see GCC bugreport) and hence does segfault on x32.

There are several suggestions on the GCC bug report to work around/fix the
issue.
