alexcrichton opened PR #14735 from alexcrichton:fix-oveflow to bytecodealliance:main:

The function drain_drop_stack could recursively call itself for each
depth in a guest controlled type, even though its purpose was to make
such a process iterative.

This PR removes the recursive calls and also adds a debug check that it
drain_drop_stack is not being recursively called.
