The stack protector will add 8 (aligned, so possibly padded) bytes to each stack frame of functions with arrays of 8 or greater bytes.  So if things are marginal, this could make the difference between Pythons compiled with/without -fstack-protector.

N.B. if rPath is compiled with -D_FORTIFY_SOURCE=2 and -O1, then -D_FORTIFY_SOURCE=2 has no effect (it is only activated at -O2 or higher).

Details on Ubuntu's compiler flag defaults:

Putting MAXPATH on the stack certainly seems like a big waste of space, though.  :)
