>Description:
When initializing an char-array with a string, the array
is not padded with NULL-bytes, if the string is shorter than
the array (e.g. char a[8]="test")
>How-To-Repeat:
/* this program should print "test@@@@" but prints "test@xxx" */
/* compile with "gcc <file>" */

#include <stdio.h>

int main()
{
   char a[8]="test",b[8];
   int i;
   char *x;

   x="xxxx";

   for(i=0;i<8;i++) if(a[i]) putchar(a[i]); else putchar('@');
   putchar('\n');
}
