Details

gcc-debug seems to contain a stray /build dir (in addition to the expected stuff under /usr).

I haven't fully got my head around debug pkgs yet but surely this cannot be correct?

It means the gcc-debug pkg is not installable in the build chroot immediately after a completed build due to file conflicts (many errors of type "blah exists in filesystem").
This task depends upon

Looking at the package, it is the go and d language source files. The distro makepkg needs backports to support languages other than C or C++...

(edit: Allan beat me to the punch :)

Looking deeper, this is likely a pacman issue, and it might already be fixed by:

Or we could drop gcc-go and gcc-d... No-one needs these anyway :)

Funny you should say that.. I've been working on some bootstrapping issues and guess where the pain points are?

In fact, gcc-d is about to become harder to build in gcc-12. Similar to the gcc-ada situation, in gcc-12 gcc-d is required to bootstrap gcc-d.

There are actually a lot of packages that drop stuff in /build. Just look at the output of `pacman -Fx '^build/' | sed -r 's/.*is owned by (\S+).*/\1/' | sort | uniq`.

I built extra/dolphin 22.08.0-1 locally and could not install its dolphin-debug package due to:
error: failed to commit transaction (conflicting files)
dolphin-debug: /build/glibc/src/glibc/sysdeps/x86_64/crti.S exists in filesystem (owned by glibc-debug)
dolphin-debug: /build/glibc/src/glibc/sysdeps/x86_64/crtn.S exists in filesystem (owned by glibc-debug)
dolphin-debug: /build/glibc/src/glibc/sysdeps/x86_64/start.S exists in filesystem (owned by glibc-debug)

Somehow the build provided by the repos does not have this problem

I guess this is related to FS#74941 and it may be fixed with FS#75092
