That indeed fails, and it passes if I use GCC 15: Good: gcc version 15.2.1 20251101 (Gentoo Hardened 15.2.1_p20251101 p1) Bad: gcc version 16.0.0 20251106 (experimental) 1139d69306d67aeeb0ee13a8d2a367933afda8e4 (Gentoo Hardened 16.0.9999 p, commit e79963c291a5666ef91c5b048db5993960266b36) I'll bisect GCC.
