_sre.c, data_stack_grow() in Py2.4 uses realloc()'ed memory without
initialising the newly allocated memory. For complex regexps that require
additional sre stack space, this ultimately results in a core dump or
corrupted heap. Filling the newly allocated memory with 0x55 makes the
problem more obv
