--- Comment #1 from Giulio Benetti <giulio.benetti at benettiengineering dot com> ---
This bug shows up also on gcc 13.2.0 while building htop with optimization -O2.
This is worked-around by disabling optimization with -O0.

that is most likely a different bug, please file it seperately.

It's not a problem, but it looks very similar to me:

Let me know if you still want me to open new bug.
Thank you!
