PF1e (CRB, Stable Characters and Recovery): characters taking continuous damage such as bleed automatically fail all Constitution checks made to stabilize, losing 1 hp per round in addition to the continuous damage. _process_dying never applied bleed (only _turn_gate, reached by active creatures did), so a bleeding dying creature lost 0 hp per round. It now ticks bleed_damage at the start of the dying turn and auto-fails the check (no d20 consumed), then evaluates death.
