Michael Kerrisk e50eaaf192 nptl.7: Note that i386 and x86-64 binaries can't share mutexes 
Quoting Nicholas Miell:

    PTHREAD_PROCESS_SHARED says any thread with access to the
    memory containing the mutex can operate on the mutex and
    POSIX basically ignores the idea that different processes
    could be running completely incompatible executables or
    whatever.

    pthread_mutex_t has a bunch of #ifdefs in the middle of it
    that change the structure size and layout between i386 and
    x86_64.

    Most importantly, the positions of the __nusers and __kind
    fields are swapped (this looks to be an oversight dating
    back to 2003 when __nusers was first introduced and carefully
    preserved when the separate i386 and x86_64 versions of
    pthreadtypes.h were merged into the single x86 version),
    which means that when the lock and unlock functions attempt
    to figure out what kind of mutex it is
    (recursive/adaptive/whatever), they'll look at the wrong
    field if the mutex is from the wrong architecture and then
    things will break.

    And then there's the fact that the rest of the struct is a
    union in the 32-bit version and flat in the 64-bit version,
    but that could have been worked around if you put a flag in
    the __kind field that tells the 64-bit pthread library that
    it is looking at a 32-bit mutex.
