Description of bug
PolyMC started segfaulting for me recenty. I'm on Arch, using Gnome 44.3 on Wayland. The issue is that debuginfo was stripped from official binary, and I can't launch latest github -debug workflow artifact, so I can't even provide a backtrace. I have these errors trying to launch it:
warning: direct reference to protected function `_ZNK18QAbstractListModel5indexEiiRK11QModelIndex' in `/usr/lib/libQt6Core.so.6' may break pointer equality
./bin/polymc: _ZNK18QAbstractListModel5indexEiiRK11QModelIndex: /usr/lib/libQt6Core.so.6: error due to GNU_PROPERTY_1_NEEDED_INDIRECT_EXTERN_ACCESS
here's the stdout of original binary, in /usr/bin:

- Get a segfault
Suspected cause
No response
This issue is unique
- I have searched the issue tracker and did not find an issue describing my bug.
That's an issue with one of the packages on the AUR, download another one
The developers of Arch Linux changed the way they build Qt6 so the binary Qt6 packages, which are built on Ubuntu, won't run on Arch.
If you need a Qt6 build with debugging symbols on Arch Linux, you'll have to install polymc source package from AUR but edit the PKGBUILD to build in debug mode instead of release mode (-DCMAKE_BUILD_TYPE=Debug).
@k1gen what did you close the issue for? If it's an actual problem then it needs to be reproduced and then patched.
I worked around this on Arch Linux by installing polymc-qt5-bin on AUR
