This code shouldn't compile, due to the array bounds error. But instead,
compiler memory corruption occurs.

int bug4252()
{
    char [] s = "abc".dup;
    s[5] = 'd';
    return 3;
}
static assert(bug4252());

The revision that fixed this also fixed a missing line number bug. Looking at
the source, it did so by calling a error function with a Loc value rather than
without it. My question is why the original function even exists? When would
the compiler ever need to dump an error message and not have a line number to
attach to it?
