To: glibc-bugs
#include <sys/types.h>
#include <sys/stat.h>
#include <unistd.h>
int main (void)
{
return fstat (0, NULL);
}
will generate segfault in glibc on all systems (i386 - i686) i have.

I think fstat should return -1 and set errno to EFAULT or EINVAL or something else. The bug definitely in glibc. glibc should check such errors.
