My piece of code is compiled with Emscripten. It contains SIMD instructions. When trying to run any twiggy function I'm getting an error. I don't know if this is an error in Twiggy or is it pointing to a valid error. All WABT tools work with this wasm file

error: WASM error: lane index out of range (at offset 10491)
caused by: lane index out of range (at offset 10491)

twiggy version:
twiggy-opt 0.7.0

👟 Steps to Reproduce

  • Run any command with the file attached
  • twiggy top -n 25 test_case.wasm

😲 Actual Behavior

Outputs
error: WASM error: lane index out of range (at offset 10491)
caused by: lane index out of range (at offset 10491)

🤔 Expected Behavior

No idea what should happen because I never used Twiggy before, perhaps should show some more verbose output with a few lines of context where the error occurred and in what symbol. Unless this is a bug and it should just work.
