In most cases when the bug is reproduceable and a single preprocessed
source is enough (e.g. not LTO build etc.), the gcc driver dumps all the
required info into /tmp/.
That is the -freport-bug
Preprocessed source stored into /tmp/ccXXXXXX.out file, please attach this to your bugreport.
So, if mock + koji copied those over (best xz or bzip2 compressed) alongside with
build.log / root.log etc. in case the build failed, that would be very much
