Yes, it sure is a weird bug. Hard to know what to make of it.
The flags in src/util/thread/mpiu_thread.c seem to be key. Looks as if
MPICH_TLS_SPECIFIER is defined at one point in the build, but not at
another point. Might need some detailed digging by someone who knows
their way around the threads configuration.
