Xcode 14.0 GCC-12 Linker Issue

My Mac updated Xcode to version 14.0. After installing the new command line tools I started running into issues with the version of ld that it ships with. More specifically I have a project I compile with the g++-12 compiler (installed via homebrew) and the linker bombs when I try to compile anything with the following output:

I've tried reinstalling all the home-brew packages but this didn't seem to affect anything.

ld gcc macos xcode

I do not have an answer but I'm seeing a similar problem with GCC-11.

I also had the same problem with GCC-11, but upgraded via brew to GCC-12 in hopes that it would solve the problem. No joy.
