debuginfod "can't read symbols: file format not recognized" GDB Errors

I was trying to keep a GDB session open for nheko when I found that I was getting some odd debuginfod messages that claimed some of the debug files it was collecting had unrecognizable file formats?

For context, I ran:

echo 0 | sudo tee /proc/sys/kernel/yama/ptrace_scope
gdb -pid $(pidof nheko) -batch -ex "set logging file kwin_x11.gdb" -ex "set logging on" -ex "continue" -ex "thread apply all backtrace" -ex "quit"

I also use a x86-64-v3 repo (that also has debuginfod support):
https://git.harting.dev/ALHP/ALHP.GO/

And I have pacman.conf for repos set up like this:

[core-x86-64-v3]
Include = /etc/pacman.d/alhp-mirrorlist

[extra-x86-64-v3]
Include = /etc/pacman.d/alhp-mirrorlist

[community-x86-64-v3]
Include = /etc/pacman.d/alhp-mirrorlist

#[testing]
#Include = /etc/pacman.d/mirrorlist

[core]
Include = /etc/pacman.d/mirrorlist

[extra]
Include = /etc/pacman.d/mirrorlist

#[community-testing]
#Include = /etc/pacman.d/mirrorlist

[community]
Include = /etc/pacman.d/mirrorlist

# If you want to run 32 bit applications on your x86_64 system,
# enable the multilib repositories as required here.

#[multilib-testing]
#Include = /etc/pacman.d/mirrorlist

[multilib]
Include = /etc/pacman.d/mirrorlist

I take it this would be a problem? I'm not used to debugging this way :v

Re: debuginfod "can't read symbols: file format not recognized" GDB Errors

Do you have the same problem when you don't use packages from that third-party repository?

Re: debuginfod "can't read symbols: file format not recognized" GDB Errors

I mean, I've been using that repo for a while, to go back would be to essentially reinstall my entire system so I wouldn't know Lol
If you're willing to help with that, you could just build nheko and attach gdb?
But really, the packages from that repo don't change the used compiler, it just grabs the upstream PKGBUILDs and builds them with -O3, (usually) LTO, and with march=x86-64-v3 via a bot (should that cause such an issue?)
