@Riki (or any other Fedora user), in case you are interested, this is my work flow:

Install gcc-latest from copr:
https://copr.fedorainfracloud.org/coprs/jwakely/gcc-latest/

Configure lyx to use it:

$ </path/to/lyx/>configure --with-version-suffix=-devel CC=/opt/gcc-latest/bin/gcc CXX=/opt/gcc-latest/bin/g++

And that is it. :-)

The previous patch was all that it was required to compile lyx-2.4 with gcc-12. :-)
