alexcrichton opened PR #14329 from alexcrichton:less-catch-all to bytecodealliance:main:

When translating a wasm call instruction into a CLIF try_call instruction it's possible that the wasm could have redundant exception handlers for the same scope. This causes a particular oss-fuzz test case to time out right now and a small, albeit not general, fix is to stop pushing handlers once a catch-all handler is reached. In such a situation it's not possible for anything further to get visited because exception processing will stop at the catch-all.
