New submission from Masahiro Konishi:
int x = PyOS_mystricmp("foo", "none");
expected: x < 0
actual: x == 0
while (*s1 && (tolower((unsigned)*s1++) == tolower((unsigned)*s2++))) {
;
}
return (tolower((unsigned)*s1) - tolower((unsigned)*s2));
The while-loop is finished when *s1 != *s2 (ex. *s1 == 'f', *s2 == 'n'), but s1
and s2 already point to next characters (ex. *s1 == 'o', *s2 == 'o'), so
PyOS_mystricmp returns difference between these characters.
