Detect Py_TRACE_REFS at runtime and calculate object offsets accordingly by lostmsu · Pull Request #1426 · pythonnet/pythonnet

What does this implement/fix? Explain your changes.

This gets rid of #if PYTHON_WITH_PYDEBUG by detecting if objects have reference tracing (e.g. Py_TRACE_REFS) enabled at runtime based on the offset of refcount field in a new object.

Does this close any currently open issues?

It should fix #1412

Any other comments?

Slight refactoring had to be done to ensure initialization code does not depend on knowing field offsets until they actually become available.
