If I understood the fix correctly, the problem seemed to be that, given an uninitialised variable, different compilers initialised it differently by default.  So the problem may have been compiler specific, and only platform specific as a consequence.

Specifically clang (the default cc on macOS) seems to be quite consistent about initialising to zero in such circumstances, which is convenient in practical terms, but can cover up the missed initialisation, until one re-tests with a different compiler (eg gcc).

Best wishes,

Norman
