On a Python built in debug mode, :c:func:`Py_DECREF()` now calls
|

``_Py_NegativeRefcount()`` if the object is a dangling pointer to
|

deallocated memory: memory filled with ``0xDD`` "dead byte" by the debug
|
||||
hook on memory allocators. The fix is to check the reference count *before*
|
||||
checking for ``_Py_IsImmortal()``. Patch by Victor Stinner.

Skip ``test_gdb`` if gdb is unable to retrieve Python frame objects: if a

frame is ``<optimized out>``. When Python is built with "clang -Og", gdb can

fail to retrive the *frame* parameter of ``_PyEval_EvalFrameDefault()``. In
|
||||
this case, tests like ``py_bt()`` are likely to fail. Without getting access
|
||||
to Python frames, ``python-gdb.py`` is mostly clueless on retrieving the
|
||||
Python traceback. Moreover, ``test_gdb`` is no longer skipped on macOS if
|
||||
Python is built with Clang. Patch by Victor Stinner.
