Incremental scan causes segmentation fault on Arm 64

[Flameborn]

I'm running Gonic from source under Arch Linux on a Raspberry Pi 4 (aarch64).

Currently, an incremental scan causes a segmentation fault and new tracks are not added to the database. My music folder consists of a few symlinks, I'm not using the multi-folder support yet.

I'm pasting The systemd log below, in case it's helpful:

thanks should be fixed

Confirmed, scans work nicely now.

Thank you so much for the quick fix.
