Is there a symbolicated crash log somewhere to look at?

This still reproduces with JSC_alwaysDoFullCollection=1 which implies it's not caused by the premature deallocation of a live object.

I should say, it's not a premature deallocation of a live object due to generational collection. We could still be blowing away a live object during a full collection.

Throwing back to Ryosuke to verify that this has been fixed.

No longer seeing the crash.
