Ahoj,
I want to collect debug information (gdb backtrace of a crash) for some KDE application (neochat-git from the AUR), and it depends on qt6-declarative and qt6-base.
I have debuginfod enabled, but it seems that for qt6-base GDB still does not download debugging information.
Where I could locally build qt6-declarative with options+=('!lto' 'debug') and -DCMAKE_BUILD_TYPE=RelWithDebInfo yielding an additional package qt6-declarative-debug, doing this for qt6-base yields to a build error[...]

(Also when I remove the !lto option I get the same -- my default makepkg options contain lto).
So, I am relying on debuginfod debug symbols here, but they seem not be provided.
Dear Artix maintainers, can you check what the issue is there, why they are not provided on your debuginfod server, and can you provide them?
Here a GDB backtrace with missing symbols for /usr/lib/libQt6Core.so.6 (and also for /usr/lib/libglib-2.0.so.0):#0 0x00007ffff4bad9ef in
