Martin Sebor commented on STDCXX-827:
-------------------------------------
It seems to me that the code in the test is just plain wrong: the {{char}}
buffer isn't guaranteed to be aligned. It needs to be aligned on the strictest
boundary (probably that of {{void*}} or {{long long}}) so that the first member
of each facet (most likely the mutex) is properly aligned.
