There are more crashes as I do parallel build:

  327 | }
      | ^

Comment 2 Martin Stransky 2020-11-18 20:18:45 UTC 
Koji Fedora 33 build is here, to reproduce it just download the src.rpm and rebuild locally:

Comment 3 Jakub Jelinek 2020-11-19 11:48:19 UTC 
Reproduced, also gcc trunk is affected, -g -O2 -std=gnu++17 -flto is enough to reproduce and the ICE is during debug info generation.
Reducing now.
