The code is wrong, the malloc is leaking, you need a free? Is windows giving errors for variable length arrays?

[pkspyder007]

Yes the compiler was throwing error for non constant array size. I don't have idea about the malloc leaking I am calling free at the end.

Something I found with wasm on windows 1- Unknown array length error 2- func i32_f32_i64_f64_ret_i32_f32_i64_f64 is retuning invalid result in test 3- scripts are not being loaded properly, e.g. empty_module.wasm is loaded from Debug folder not from script path 4- wasmtime dll and lib not being copied to build output

Solved.
