--- Comment #11 from Richard Biener <rguenth at gcc dot gnu.org> ---
So I think I can reproduce, but it simply computes forever(?):

3649942 rguenth+  20   0  0.242t 0.242t  20852 R 100.0 52.66  52:25.09 d21     
3664619 rguenth+  20   0   50172  30752  14580 R 100.0 0.006  50:38.87 cc1     

that's

both in stagefeedback.  Luckily I have 0.5TB of memory in this machine.
