Debug build uses the same ABI as release build
-----------------------------------------------
Python now uses the same ABI when built in release and in debug mode. On Unix,
when Python is build in debug mode, it is now possible to load C extensions
built in release mode and C extensions built using the stable ABI.
Release build and debug build are now ABI compatible: the ``Py_DEBUG`` define
no longer implies the ``Py_TRACE_REFS`` define which introduces the only ABI
incompatibility. A new ``./configure --with-trace-refs`` build option is now
required to get ``Py_TRACE_REFS`` define which adds :func:`sys.getobjects`
function and :envvar:`PYTHONDUMPREFS` environment variable.
(Contributed by Victor Stinner in :issue:`36465`.)
On Unix, C extensions are no longer linked to libpython. It is now possible to
load a C extension built using a shared library Python
with a statically linked Python.
(Contributed by Victor Stinner in :issue:`21536`.)
On Unix, when Python is built in debug mode, import now also looks for C
extensions compiled in release mode and for C extensions compiled with the
stable ABI.
