There was a problem hiding this comment.
I realized I misunderstood how BeginTryTable/EndTryTable work. This is a new part of the code for me. BinaryReaderInterp::OnTryTableExpr calls EndTryTable after catch blocks are processed, not after the end.
In this case this is not needed (although harmless), and the normal OnEnd should call RestoreLocalRefs (it does).
I am sorry, I will submit another fix.
