In particular, see https://trac.macports.org/ticket/70641#comment:39 and https://trac.macports.org/ticket/70641#comment:45 for an explanation of why this is happening in macOS 15, and why it’s x86_64-specific. This bug will also affect macOS 14 with Xcode 16, as that build configuration uses the macOS 15 SDK.
This is on file upstream at https://gcc.gnu.org/bugzilla/show_bug.cgi?id=116809.
