The simple program:

        c = -2147483648 / -1
 
        a = 1
        b = 0
        c = a / b
 
        print *, c
 
        end

gets this error:

Obviously, it attempted to evaluate a constant expression
that it couldn't do.  Interestingly, it got the line number
wrong, as the error was not on source line 5 (it was really
on line 3).

This was compiling with  f77 -g -o foo foo.f
