Bug report

Bug description:

Compile a stable ABI extension module with the filename "something.abi3.so" (or .pyd on Windows)

Run python -c "import something"

A freethreading build will attempt to import the extension module, even though it explicitly isn't compatible with the stable ABI. This (unsurprisingly) leads to a crash.

Tested on beta 3.13.0b2 (but a quick search didn't find relevant changes after that)

CPython versions tested on:

3.13

Operating systems tested on:

Linux
