            Bug ID: 25799
           Summary: setuid(0) hangs on power BE with tsan
           Product: compiler-rt
           Version: unspecified
          Hardware: Other
                OS: Linux
            Status: NEW
          Severity: normal
          Priority: P
         Component: compiler-rt
          Assignee: unassignedbugs at nondot.org
          Reporter: seurer at linux.vnet.ibm.com
                CC: llvm-bugs at lists.llvm.org
    Classification: Unclassified

The test cases projects/compiler-rt/test/tsan/setuid.c and
projects/compiler-rt/test/tsan/setuid2.c hang when run on power big endian.  It
works fine on little endian.  Note that tsan was just recently activated for
power.  To duplicate the failure just run make check-all on a power big endian

>From the comment in setuid.c it looks like this is something that has happened

// Setuid call used to hang because the background tsan thread did not handle
// SIGSETXID signal. Note that we don't care whether setuid call succeeds
// or not.
