Crash: double free or corruption with libcava 0.10.7

[Times-Z]

Describe the bug:

Hyprpanel crashes immediately upon startup with a memory corruption error (double free or corruption / corrupted size vs. prev_size). This is caused by an incompatibility with the latest libcava update (version 0.10.7).

To Reproduce:

Steps to reproduce the behavior:

• Update system packages, specifically libcava to version 0.10.7-1.

• Ensure the cava widget is enabled in your Hyprpanel configuration.

• Launch hyprpanel from the terminal.

• See the crash log and core dump.

Expected behavior Hyprpanel should launch and render the audio visualizer without memory corruption.

Logs:

hyprpanel-Message: 07:01:27.300: OSD: 14.4ms
corrupted size vs. prev_size while consolidating
/usr/share/hyprpanel/hyprpanel-app: line 8: 25079 Aborted (core dumped) LD_PRELOAD="" /sbin/gjs -m $file $@

Desktop:

• Distribution: Arch Linux

• Window Manager/Desktop Environment: Hyprland

• GJS Version: 1.86.0

• Libcava Version: 0.10.7-1 (Broken) / 0.10.6-2 (Working)

Additional context:

The crash is consistently reproducible on gjs 1.86.0. Downgrading libcava to 0.10.6-2 immediately resolves the issue, confirming that the memory corruption is linked to how Hyprpanel/Astal interacts with the new libcava buffers. Running with G_MESSAGES_DEBUG=all shows the crash happens right after OSD initialization when the audio modules start.

Does this occur for your if you go to your ~/.config/hyprpanel/config.json and remove cava from all your layouts?

[Times-Z]

Nope
When I remove cava from all the actives modules the problem isn't present
That's my "fix" for now

Any updates on this?
