this has been fixed as of version 1.40

foo(n)
int n;

        int z[n];

void main()

          This is so wrong as to be beyond belief.


With bugs and computers, it is hard to find something beyond belief.


It certainly was a relatively straightforward bug to introduce, and it
probably wasn't all that hard to fix. Certainly the existence of this
bug is not an indication that gcc is not a good compiler. In fact, it
is an excellent compiler. And the price is very hard to beat.
