[issue2242] Decoding UTF-7 with "ignore warnings" crashes Python on Windows Vista

[Hirokazu Yamamoto]

Hirokazu Yamamoto added the comment:

I reproduced this bug with VC6 + Win2000SP4 + following code.

'+\xc1'.decode("utf7", "ignore")

and this simple patch prevented crash.

-        Py_UNICODE ch;
+        char ch;
         restart:
         ch = *s;

Probably this is due to integer conversion, but I didn't look at logic
