When you said "hang up", I didn't understand what you meant.

Now I see, it actually hangs dmd (actually, it's not hung, it is still 
running as far as I can tell).

If I reduce to 10000, it completes the compile with an error.

I think it has to do with parallel(s).

In fact, this code also hangs:

int main(string[] argv)
{
    string s[100000];
    parallel(s);
}

In order to get what you really do want (no hangs, no errors), use this:

parallel(s[])

I'll file a bug on this.
