🚀 go-pugleaf

OS: SunOS 4.0
Compiler: gcc/g++ 2.1 (using GNU ld 1.9, GNU as, 1.38)
Machine: Sun3/260

This bug has been reported already for gcc-1.40 but it still exists
for 2.1 so I am re-posting it.

Undeclared variables inside an array index in a call to "new" can generate
internal compiler errors.  The following code

struct foo
{
    int a;
    foo() : a(0) {}
};

struct bar
{
    foo * x,y;
    bar() 
    {
	x = new foo[(n+1)*(m+1)];
	y = new foo[(n+1)*(m+1)];
    }
};

Gives the following output:
