I seem to recall finding dummy stackframes in AIX code in the
middle of functions, usually where the code had a set of nested
{}'s with some declarations inside them, which seemed to get a
new stackframe for storage. I'm going back 10 years now though,
when I was trying to write a function to dump out the stacktrace
on various different unix systems (which I never got to work on
AIX as a result of the extra stackframes).
