closes #82933

#82933 was fixed by #83108 but it failed to have a testcase, because no MCVE was present at that date.

I was able to get some from an older ICE of mine (#74318), so here we are now :)

Hm, #83108 doesn't seem like it fixes anything - it just removes function definitions. Did you typo that perhaps?

Otherwise r=me

You're absolutly right!
It was fixed in 9d9c2c9 so probably #84168 which already adds a testcase for it!
Thank you for bringing it up. I'm closing this and the linked issue.
