------- Comment #2 from rguenth at gcc dot gnu dot org 2008-08-20 09:41 -------
Interesting. Can you attach preprocessed source? I suspect this bug may
show/hide based on libc implementation details (toupper can be a macro).

The __ctype_toupper_loc function, differently than the bad case is called only
ONCE in this code.

The preprocessed sources for strncasecmp.c are exactly the same for both cases.
