[Bug c/43556] New: Ubuntu : segmentation fault in strchr() obtained with gcc4.4.3 and not with gcc4.4.1

[eric dot cabret at gmail dot com]

My system is Ubuntu 64 bits Lucid Lynx.
with this following small program, I obtain a crazy segmentation fault in
strchr() with gcc4.4.3-4ubuntu5 AND NOT with gcc4.4.1-4ubuntu9 (with same glibc
in both case) :

// gcc (Ubuntu 4.4.3-4ubuntu5) 4.4.3 -> execution gives a "segmentation fault"
// gcc (Ubuntu 4.4.1-4ubuntu9) 4.4.1 -> execution is fully OK
#include <stdio.h>
#include <string.h>

char t[]="It: is a gcc4.4.3 bug";

main() {
char *p;

puts(t);
p = strchr(t, ':');
printf("p='%s'\n", p);

return 0;
}

Many best regards.
Eric.
