Possibly try   *rval = OBJECT_TO_JSVAL(NULL);
Alternatively, you can make the constructor throw an exception
on error.

Also, it might be useful to check out JS_IsConstructing() which allows
your constructor to detect when it's being called as a constructor with
"new" or as a plain function (i.e. var custom = Custom()) and act
accordingly (you can actually get assertions related crashes otherwise
if SpiderMonkey was compiled with debugging support)...
