Package: libc6
Version: 2.5-6
Severity: normal
Hi,
there happens a segmentation fault with the following code:
#include <stdio.h>
int main(int argc, char**argv)
{
printf("%s\n", strerror(atoi(argv[1])));
}
I have observed this on amd64 libc6 2.5-5 and 2.5-6,
it does not occur on i386 libc6 2.5-5.
The amd64 system is actually an amd64 schroot running on a sarge/i386
host.
If there is anything I can do to help you debug this, please let me
know. A small test log is appended below.
