How to handle panic, abort or trap?

[daxpedda]

Currently the wasm32-unknown-unknown target has no support for unwinding, panic=abort is the only option.
Also, as far as I'm aware, there is currently no work being done to bring the exception handling proposal to Rust: rust-lang/rust#58874.

My question: is there some kind of strategy that can currently be used to abort WASM execution?

As far as I understand, panicking can leave behind a corrupted state, because Drop handlers are never called, which can be problematic for things like Rc for example. Currently panic simply emits a trap instruction, the browser then aborts the current function and throws an error in JS.
But any other functions running will continue, like promises or event handlers.

Can this be stopped somehow? Can the WASM module be invalidated somehow?
