            Bug ID: 49356
           Summary: bug_taskwait_detach failing on 32-bit x86 Linux
           Product: OpenMP
           Version: unspecified
          Hardware: PC
                OS: Linux
            Status: NEW
          Severity: normal
          Priority: P
         Component: Runtime Library
          Assignee: unassignedbugs at nondot.org
          Reporter: lukebenes at hotmail.com
                CC: llvm-bugs at lists.llvm.org

Since tasking/bug_taskwait_detach.cpp was added in 3c31b78455da, I'm seeing the
failure below on x86 but not on x86-64. I've confirmed this issue on clang
built by both gcc 10 and clang 12.
