Please let me know if you need any extra info.
Comment 2 Jakub Jelinek 2021-01-12 15:32:11 UTC 
Martin, that is likely your code, and the r11-6532 fix is in -0.12 already, so it must be something else.
Comment 3 Jakub Jelinek 2021-01-12 15:34:04 UTC 
I mean Martin Sebor, not Martin Stransky, sorry for not being clear.
