Re: python/dist/src/Objects unicodeobject.c, 2.228, 2.229
Applied patch for [ 1047269 ] Buffer overwrite in PyUnicode_AsWideChar.
Python 2.3.x candidate.
why bother? the unicode object you're copying to holds size+1 characters, so all the code does is copying an extra NULL character... completely harmless. </F>

That's true for Py_UNICODE, but not necessarily for the wchar_t* buffer your dealing with. -- Marc-Andre Lemburg eGenix.com Professional Python Services directly from the Source (#1, Oct 15 2004)

oh, I missed that the patch modified two functions... (and overwriting the null char in FromWideChar is only a good idea if you're overwriting it with another null character...) </F>
