           Summary: [3.0] Non-determinism in self-host on x86-32 linux
           Product: new-bugs
           Version: unspecified
          Platform: PC
        OS/Version: Linux
            Status: NEW
          Severity: normal
          Priority: P
         Component: new bugs
        AssignedTo: unassignedbugs at nondot.org

Using the script utils/release/test-release.sh to do a Release clang self-host,
on 64 bit linux I see the following:

# Comparing Phase 2 and Phase 3 files
file CommandLine.o differs between phase 2 and phase 3
file Path.o differs between phase 2 and phase 3

This is normal: these two files have the path and or date embedded in them
(that should be fixed if possible, but that's another story).

However on 32 bit linux I see:
