Suspected Inconsistency

[Martin v. Loewis]

> Could You please comment on this ?

Thanks for your bug report. My comment is very simple: I cannot
reproduce the problem you report. Please have a look at

http://gcc.gnu.org/cgi-bin/fom.cgi?file=11

for information how to report bugs; more is explained in the section
"Reporting Bugs" of the gcc manual.

I've tested the program

#include <ctype.h>

int main()
{
  toupper('a');
}

on i586-pc-linux-gnu, with glibc 2.1.3pre1. Under no combination of
command line flags, with either gcc 2.95.2, or egcs 1.1.2, I was able
to produce the message you see.

Most likely, it is a bug in the C library, which most likely has been
corrected.

Regards,
Martin
