I know, but I can't reproduce it at will. And debug-on-error didn't help
catch it in the act, maybe there is some condition-case involved
somewhere that should have better been a condition-case-unless-debug.

No config using flymake and none for eglot. The only thing I did is
put eglot-ensure on c-mode-common-hook.
Maybe I can catch it in LLDB somehow, but that will have to wait a bit,
unfortunately.
Anyway, thanks for the replay.
