------- Comment #1 from deewiant gmail.com  2007-06-16 09:14 -------
Brought it down to this, nothing to do with strings but rather with the
attempted and failing CTFE of toString (here simplified and renamed f):

int f() {
        // this also causes the crash:
        // int[] a = void;
        int[1] a = void;
        a[0] = 1;
        return 1;
}

const i = f();

It's probably dependent on Issue 1254, but they're subtly different so I won't
set it as a dependency.
