"free" function is absent though "malloc" exists about wasmer-python HOT 4 CLOSED

Hello,

The same way you export a malloc and a setImage functions, you should also export a free function. Check the greet example (the greet.rs file and the greet.py file).

from wasmer-python.

The thing here is that I don't explicitly import "malloc", but it's presented. My compilation commands looks like this:
emcc -O2 src/Graph.cpp src/Selection.cpp -o core.wasm -s EXPORTED_FUNCTIONS='["_setImage", "_getMask", "_updateSelection"]' -s EXTRA_EXPORTED_RUNTIME_METHODS='["cwrap"]' -s TOTAL_MEMORY=268435456
So, no "malloc" in "EXPORTED_FUNCTIONS". And when you use wasm from JS both "malloc" and "free" functions are presented.

The easy solution is just to make wrapper for "free" function and call it inside, but it looks like both have to be supported by default.

Personally, I would open an issue on emscripten to understand why free isn't exported by default. If malloc is, it is correct to assume free should be exported too.

Closing as it's not related to this package itself.

Please feel free to raise your voice if you need further help, or if you believe this project is responsible of addressing this issue.

Thanks!
