WebAssembly GC and New Exception Handling Issue

This repository contains a simple reproducer for the issue of using GC struct types in combination with the new Exception Handling proposal.

Description of the Issue

In case of usage of a ref as the result of a try_table block, I constantly receive the following exception:

wasm-function[1]:0x4b: RuntimeError: unreachable

I reproduced the issue with V8 versions from 12.4.94 to 12.5.104. I didn't check it for the earlier versions.

How to run the reproducer

This requires the V8 shell (d8) and wasm-tools to be installed on your machine.

Tu run the reproducer, use make:

make D8_PATH=/path/to/your/d8

Change the reproducer.wat file to play around the reproducer.
