[issue31426] [3.5] crash in gen_traverse(): gi_frame.ob_type=NULL, called by subtract_refs() during a GC collection

It seems I have the same segfault, but with 3.6.13 python shipped with SLE15SP2. It's salt-api process under intensive usage. I'm able to reproduce it, but can't isolate due to the service complexity. In some cases it takes about 5 minutes to be crashed, but in others it could run with no crash for about an hour or more (I keep the workload on this service with a kind of stress test).
