alexcrichton opened PR #6776 from alexcrichton:trap-on-misalignment to bytecodealliance:main:

Previously Wasmtime would return EINVAL to a guest but the upstream documentation indicates that misaligned pointers should trap, so this commit updates the alignment error to get converted into a trap rather than than being returned to the guest.

I merged the pointer out of bounds changes upstream, so you can also change the PtrOutOfBounds and PtrOverflow cases to trap.

The new preview 1 implementation inside wasi/src/preview2/preview1 should also be updated as well. Unfortunately, it looks like instead of using a From<GuestError> impl there, it instead uses a pattern of Result<_, GuestError>::or(Err(Errno::Inval)) at each call site, so that is a tougher job. Its OK to not take that on as part of this PR, but we should file an issue on it if you want to defer it.
