Description

@pablogsal

PR#30872 added_Py_DECREF_SPECIALIZED which callsdestruct over the object. Whendestruct isPyObject_Free this skipstracemalloc counting reporting that the memory is alive. This also makes debuggers segfault because they think that the object is alive because they did not get a notification. This is the code that's not getting called:

cpython/Objects/object.c

Lines 2924 to 2928 in2e950e3

struct_reftracer_runtime_state*tracer=&_PyRuntime.ref_tracer;
if (tracer->tracer_func!=NULL) {
void*data=tracer->tracer_data;
tracer->tracer_func(op,PyRefTracer_DESTROY,data);
}

This may also qualify a regression as makes tracemalloc detect incorrect memory usage for these objects
