This update breaks long-path support in Windows. It includes the following unnecessary check, which is using the wrong comparison operator:
if (len >= PY_SSIZE_T_MAX / sizeof(wchar_t))
PyMem_RawMalloc already checks this and returns NULL if size > (size_t)PY_SSIZE_T_MAX. This bug is causing a MemoryError with long paths:
>>> p = 'C:/Temp/longpath' + ('/' + 'a' * 255) * 9
>>> os.chdir(p)
>>> len(os.getcwd())
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
