At present, it happens that `FRAME_CLEARED` is not numerically equal to any member of `enum _frameowner`, but that could change in the future. The code that incorrectly assigned `owner = FRAME_CLEARED` was deleted in commit a53cc3f49463e50cb3e2b839b3a82e6bf7f73fee (GH-116687). Remove the incorrect checks for `owner != FRAME_CLEARED` as well. files: M Python/frame.c diff --git a/Python/frame.c b/Python/frame.c index 9a865e57d97cc6..6eb32bcce0b799 100644 --- a/Python/frame.c +++ b/Python/frame.c @@ -40,7 +40,6 @@ _PyFrame_MakeAndSetFrameObject(_PyInterpreterFrame *frame) // here. assert(frame->frame_obj == NULL); assert(frame->owner != FRAME_OWNED_BY_FRAME_OBJECT); - assert(frame->owner != FRAME_CLEARED); f->f_frame = frame; frame->frame_obj = f; return f; @@ -51,7 +50,6 @@ take_ownership(PyFrameObject *f, _PyInterpreterFrame *frame) { assert(frame->owner != FRAME_OWNED_BY_CSTACK); assert(frame->owner != FRAME_OWNED_BY_FRAME_OBJECT); - assert(frame->owner != FRAME_CLEARED); Py_ssize_t size = ((char*)frame->stackpointer) - (char *)frame; memcpy((_PyInterpreterFrame *)f->_f_frame_data, frame, size); frame = (_PyInterpreterFrame *)f->_f_frame_data;
