The only information I can contribute to this discussion are the results 
our Continuous Integration Server currently creates when building x86_64 
tools with the RTEMS Source Builder:

almalinux 8.7: OK           [gcc (GCC) 8.5.0]
debian 11: OK               [gcc (Debian 10.2.1-6) 10.2.1]
fedora 37: Failure          [gcc (GCC) 12.2.1]
opensuse-leap 15.4: Failure [gcc (SUSE Linux) 12.2.1]
ubuntu 22.04: Failure       [gcc (Ubuntu 12.1.0-2ubuntu1~22.04) 12.1.0]

These builds were for RTEMS 6 and RSB 
GIT_HEAD="bfed51462eafcb6a5102a2d6d80b233f3c6ef635".

The build failures all happen when `building: 
grub2-2.06-x86_64-linux-gnu-1` which is the last build step. There are 
several similar errors. These are two of them taken from the build log:

cc1: all warnings being treated as errors
util/mkimage.c: In function ‘grub_install_generate_image’:
util/mkimage.c:1386:41: error: dangling pointer to ‘tmp_’ may be used

Maybe one needs a new version of grub sources for gcc 12?
