Symptomless bug, but the reinterpret_cast I just introduced in bug 506721 would actually be kind of dangerous if the value were used. It's not.

Uh, to clarify, it's not the reinterpret_cast that's dangerous. That INT_TO_JSVAL was already meaningless before my change.

The change in bug 506721 didn't affect the meaning of that code, except I guess it might flunk an assertion now.

The patch for bug 507573 had a s/OBJECT/INT/ thinko affecting the line in question. Better to use null or undefined, since the getter never reads *vp and only writes it, for sure.

dvander reports that bug 506721 causes an assertion in debug browser builds. This might fix it. If not, the assertion is catching a thinko somewhere else...

Isn't the bug dvander filed bug 509557 ? It's different, but there could be more like it.

Right, my patch in bug 506721 added two assertions, each of which trips on every debug browser startup, due to pre-existing bugs. The first is bug 509557. I don't see the other one on file yet. Maybe I'm searching wrong.
