[Bug c/39113] New: no warning that a variable may be used uninitialized

[dhill at clusterresources dot com]

$gcc -O -Wextra -save-temps um3.c
$

um3.c

#include <stdio.h>

main()
{
char *J;

if (rand())
  J = NULL;

printf("\ntest %s\n",J);
}


In this example, J could be used uninitialized but the compiler is not giving
that warning.
