  Issue #2620: Overflow checking when allocating or reallocating memory
  was not always being done properly in some python types and extension
  modules.  PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
  all been updated to perform better checks and places in the code that
  would previously leak memory on the error path when such an allocation
  failed have been fixed.
