--- Comment #7 from Stefan Liebler <stli at linux dot vnet.ibm.com> ---
At least for s390: The reload of the tid does not happen in pthread_join() on
64/31bit if glibc is build with -O2/-O3 with different versions of GCC.
I only saw it on 31bit if glibc is build with -Os.
Then, you see the symptoms from time to time with testcase intl/tst-gettext6.
But you don't need gettext() to trigger it.
