The Merge node for merging exceptions into the catch environment had type kWord32, which is not a reference type. Because of this the GC does not visit it and can collect it too early. Change the type to kTaggedPointer. Also change the type of ExceptionLocation() from IntPtr to TaggedPointer for consistency. This one does not affect correctness because the IfException node is already marked as tagged.

The checks for assignemnts to member during prefinalizers assumed the slot has to live. It was assumed that if a slot is dead then we would not be updating it. Prefinalizers are allowed to touch dead objects and thus are techincally allowed to write to dead slots. Such writes are usually redundant (the object will be swept soon anyway) but are not always easy to get rid of.
