No worries, really. You don't have to apologize for reporting something.
I prefer, and by far, to deal with duplicates than with lack of reports!

OK!

Thank you. Indeed, it's the same that Ilya already reported and that comes
from something illogical in this version of gcc. We have not identified any
easy workaround for this one, in the worst case it might end up with a
pragma in the code around it :-/  I must confess I'm a bit more concerned
about the reliability of code that is emitted with such mistaken
assumptions though.

Thanks,
Willy

we observed gcc-12 issues

I agree with Tim there's nothing wrong in reporting issues. it would be
duplicate in worst case scenario, no worry

Is this something the community already knows about, or should I share
the transcript?



I'd say: Create an issue at https://github.com/haproxy/haproxy/issues. 
In the worst case it's just a duplicate and will be labeled as such.


In the ideal case you would've simply shared the logs, the effort to 
reply to your email is similar to triaging an issue :-)


Best regards
