SunOS sund6 5.7 Generic_106541-10 sun4u sparc SUNW,Ultra-250 
>Description:
Following program doesn't produce any compilation error.

main.c
{
 int a[0];
 
 printf("\n a[0] = %d \n", a[0]);
}

The output I get on different SunOS machines is always
5.
>How-To-Repeat:
Just compile the attached file "sample.c" using gcc
(version 2.95.2) on some SunOS machine and run it.
>Fix:
The compiler must not allow an array of size 0 to
be declared.
