Getting the error:

./wasm2js ../../../Babylon.js/packages/tools/babylonServer/public/havok/HavokPhysics.wasm -o ../../../Babylon.js/packages/tools/babylonServer/public/havok/HavokPhysics.js

unhandled unaligned store
UNREACHABLE executed at /src/src/passes/AlignmentLowering.cpp:334!

Research direction

Reproduce the failure with the provided wasm2js command and HavokPhysics.wasm input. Start at src/passes/AlignmentLowering.cpp:334 and investigate the unhandled unaligned store; done means the input no longer aborts at that location and wasm2js completes successfully.
