[New-bugs-announce] [issue46596] PyLineTable_InitAddressRange isn't exported - causing C Extensions to fail at import

[Nathan Shain]

New submission from Nathan Shain <nathan at rookout.com>:

I'm trying to develop C++ Extension that needs to access the new line table. I have a call to PyLineTable_InitAddressRange in my extension. After compiling, "_PyLineTable_InitAddressRange" symbol is undefined in the .so (which is ok so far).

When importing the extension, it fails with this error:

ImportError: /usr/foo/foo.cpython-310-x86_64-linux-gnu.so: undefined symbol: _PyLineTable_InitAddressRange

Obviously python isn't exporting this symbol, and making the dlopen fail

I'd make a PR with a fix, but I'm not sure which approach is appropriate
