Summary: illegal use of malloc/free

Initial Comment:
com_factor() in compiler.c uses malloc/free, but should
use PyMem_Malloc/_Free.

The use of malloc/free is fatal when one has changed
Python's allocators to use something else than
malloc/free since the stuff malloc:ed there can later
on be (attempted to be) freed through a call to PyMem_Free.

Yup, should be backported.

But note that pymalloc is known to be buggy in 2.2.x, and 
we're not going to fix that.

Ah, that should definitely be backported to releasebranches.

Just noting that current CVS already uses PyMem_ in 
com_factor.
