to the signed max value similar to 2.5 and trunk. 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.
