Methinks that

egrep 'DECREF\([a-zA-Z0-9_]->[a-zA-Z0-9_]+\)' */*.c

gives a good overview - you should never DECREF a variable on heap.
In the trunk, this command finds 36 candidates. Now, some of them
are in tp_dealloc methods, so they shouldn't cause problems - but
it can't hurt to replace them with Py_CLEAR, either.

Regards,
Martin
