Description Dimitri Papadopoulos 2000-06-10 21:33:52 UTC
Run this program under a C locale (not en_US):

#include <wctype.h>
#include <locale.h>
int main() {
    setlocale( LC_ALL, "" );
    towupper( 0 );
    return 0;
}

glibc-2.1.92 fixes this (basically, wide character support in glibc 2.1 was fairly incomplete)

Comment 3 Kurt Kaiser 2002-05-02 04:19:26 UTC
This was a "typo" in locale/C-type.c which was fixed at rev 1.22.2.4 in the 
glibc-2-1 branch.  It missed being in glibc-2.1.3 series rpms by about two
weeks.  The segfault is still present in glibc-2.1.3-23.src.rpm, 17 months
after it was fixed.

It is possible that the segfault can be avoided by setting a LANG environment
variable. I patched my glibc and don't want to revert to check that out.

ah, the bug in C-ctype.c was fixed at 1.22.2.5 on 15 Mar 2000
