When calling strxfrm on "aa" under the bokmal locale, it seems that there is
some sort of uninitialized read occurring in glibc. (I was trying to debug
something else in perl, and found I had a valgrind warning). I can get it
down to this test program, which I believe is strictly ANSI conformant:
#include <locale.h>
#include <stdio.h>
#include <stdlib.h>
#include <string.h>
int main (int argc, char **argv) {
char *result;
char buffer[256];
argv++;
if (!*argv)
return 1;
result = setlocale (LC_ALL, *argv);
if (!result) {
fprintf (stderr, "Could not set locale to '%s'\n", *argv);
exit (1);
}
while (*++argv) {
printf ("result for '%s' is %d\n", *argv,
strxfrm (buffer, *argv, sizeof(buffer) - 1));
}
return 0;
}
when run this this under valgrind I see errors:
$ valgrind ./test_strxfrm bokmal aa

I'm trusting that valgrind is correct, and that these warnings indicate
a real bug. In my experience valgrind always has been accurate in what it
reports.
