            Bug ID: 30202
           Summary: notify_all_at_thread_exit seg faults if run from a raw
                    pthread context.
           Product: libc++
           Version: unspecified
          Hardware: PC
                OS: Linux
            Status: NEW
          Severity: normal
          Priority: P
         Component: All Bugs
          Assignee: unassignedclangbugs at nondot.org
          Reporter: ben.craig at codeaurora.org
                CC: llvm-bugs at lists.llvm.org, mclow.lists at gmail.com
    Classification: Unclassified

std::thread's ctor allocates a __thread_struct, and stuffs it in a thread local
variable.  std::notify_all_at_thread_exit tries to use that __thread_struct.

If a thread is created with pthread_create instead of std::thread, then the
__thread_struct never gets allocated, and std::notify_all_at_thread_exit seg
faults.
