This works for me with GCC 4.6.0 --

[nicola@lampone ~]$ cat x.c
#include <string.h>

int g(char *);
int f(void)
{
  char *s;
  strcpy(s,s);
  return g(s);
}
[nicola@lampone ~]$ gcc x.c -Wall -c -O2
x.c: In function ‘f’:
x.c:8:3: warning: ‘s’ is used uninitialized in this function [-Wuninitialized]
[nicola@lampone ~]$

The same doesn't work with GCC 4.1.2, where the same gcc command generates
no warnings at all.

So it looks like the problem has been fixed :-)

Thanks
