CPython-WASM interpreter (python.wasm) never exits the program when it is built on WASI-SDK 27 #137580
Description
Bug report
Bug description:
Hi. WASI-SDK has been updated to 27 from 25.
I updated it and built CPython-WASM interpreter (python.wasm).
Compiled well.
However, it hangs a program and never exits the program.
For example, at the last step of building python.wasm,
i.e.) Tools/wasm/wasi.py build -- --config-cache --with-pydebug
there's a simple version check step.
i.e.) python_3.14.0rc1/python/cross-build/wasm32-wasip1/python.sh --version
it hangs forever.
I have to interrupt by Ctrl+C and then it prints like this:
python_3.14.0rc1/python/cross-build/wasm32-wasip1/python.sh --version
Python 3.14.0rc1

Tested on wasmtime 35.0.0 and wasmedge 0.15.0
And I did double check with WASI-SDK 25, everything was fine.
Thank you.
