Worked on the WasmEdge/WasmEdge repository to enhance the stability of WASI host interactions by addressing a critical memory alignment issue. Applied C++ and system programming expertise to implement alignment enforcement within WASI host functions, preventing misaligned pointer access that could lead to crashes or undefined behavior. Developed comprehensive unit tests to validate both correct pointer alignment and error handling for misaligned cases, ensuring robust host function reliability. The work focused on improving runtime safety for WebAssembly modules relying on host memory operations, with all changes tracked through targeted commits. Emphasized correctness and maintainability using C++ and unit testing practices.
