// This test is failing on powerpc64 (VMA=44). After calling pthread_cancel,
// the Thread-specific data destructors are not called, so the destructor
// "thread_finalize" (defined in tsan_interceptors.cc) can not set the status
// of the thread to "ThreadStatusFinished" failing a check in "SetJoined"
// (defined in sanitizer_thread_registry.cc). It might seem a bug on glibc,
// however the same version GLIBC-2.17 will not make fail the test on
// powerpc64 BE (VMA=46)
