the "method name" is "result" which is *not* bad. otoh, JS_InternString really
did return 0 because it ran out of memory.

reproducable? yes :)

code:
        str = JS_InternString(ccx, info->GetName());
        if(!str)
        {
            NS_ASSERTION(0,"bad method name");

note that the code should not use NS_ASSERTION(0,...) nor should it assert that
you can't run out of memory.
