hi,

yes, can confirm in debian unstable with g++-15. more precisely

ii g++-15-aarch64-linux-gnu 15.2.0-1 arm64 GNU C++ compiler for aarch64-linux-gnu architecture

this affects aarch64, ppc64el, amdv3 on Ubuntu. it does not affect current baseline amd (amdv2). haven't had the time to deep dive. Here's an example failing on amdv3 :
