Message81544
The following code segfaults on platforms where HAVE_USABLE_WCHAR_T is
not defined (for example: narrow unicode build and sizeof(wchar_t)==4)
>>> from ctypes import *
>>> import ctypes.util
>>> CDLL(ctypes.util.find_library('c')).wcslen(u'text')
(it works if the argtypes member is defined)
The reason is a non initialized structure, and the correction is trivial:
