dhil opened PR #14447 from dhil:stack-switching-regression-test to bytecodealliance:main:

As I started working on issue #13298, I realised that it has already been fixed by one of the previous stack switching PRs. Thus, this patch simply adds the PoC from the issue as a regression test.

Resolves #13298.

I think this is the last of the known issues regarding VM state corruption due to stack switching. I will look into the missing stack bounds checking / defense-in-depth checking issues next.
