Well, that much is obvious.  What's probably not so obvious is *why*
the "variable thingy" is not initialized.  From what I can tell, this
could only happen if, and only if, PfFlagArrSize <= 0.  In that case,
the body of the for loop will never execute and PfFlag will *not* be
set, hence the error.
