There was a problem hiding this comment.
Looks harmless enough to me.

Yes, it seems that the change should not be needed. Related discussion which was adopted in Belfast https://wg21.link/P0883. I wonder why clang-20 is not happy. |

i've still been snooping around what the upstream problem may be as I'd rather not commit this (easy to become cruft which is never removed). I did find gcc-mirror/gcc@613f8dd which for a moment I thought was the fix, but that is actually in gcc15... so maybe that's what broke things 😁 |

With clang 20 + libstdc++15 this code is erroring out with
afaict the code is correct for c++20, but this combination of compiler + stdlib seems to be unable to determine that
timer_state_tis default constructable (well I think that's the problem). The annoying thing is I wasn't able to reproduce this in a smaller test case, so I wonder if something else is goofy. I don't really want to make this change so sending up as draft to see if anyone else has thoughts.
