Thanks for your quick answer and the update on the bugtracker ! In a way, I'm relieved it's not my code's fault ;)

I will keep an eye on this bug report.

Am I missing something important or does that look like a GCC bug ?
It's a bug. It started with https://gcc.gnu.org/r271510 and was fixed
in the master branch by https://gcc.gnu.org/r11-963 which was
addressing https://gcc.gnu.org/PR95493 which is a different bug.

PS: result is correct with trunk version of GCC in godbolt, does that
mean it is an already solved bug?
Looks like it, but I've added a comment to PR 95493 so that it can be
investigated and we can be sure your problem is really fixed.
