The most likely culprit is that some of the code is using PyMem_Free on 
a pointer allocated with PyObject_Malloc (or vice-versa). This has 
always been illegal, but prior to 2.5 the Python memory allocator tied 
itself in knots to try to avoid crashing when client code broke the 
rules. The changes in 2.5 to release unused memory back to the OS 
required that those knots be cut.

The what's new document for each release is a good resource for these 
kinds of problems, especially its porting section:

Cheers,
Nick.
