Description

I have a dump which, somehow, has a true loop in the stack:

  ffffff050e70bee0 0xffffff050e70bee0()
  ffffff050e996050 0xffffff050e996050()
  ffffff050e70bee0 0xffffff050e70bee0()
  ffffff050e996050 0xffffff050e996050()
  ffffff050e70bee0 0xffffff050e70bee0()
  ffffff050e996050 0xffffff050e996050()
  ffffff050e70bee0 0xffffff050e70bee0()
  ffffff050e996050 0xffffff050e996050()

::findstack should abort, rather than following that loop indefinitely

The thread in question is TS_FREE, which I suppose may be relevant to how we got into this state.
