Segmentation fault with Qt6 on aarch64 Raspberry Pi OS "Bookworm"

[gustafla]

Hi. I'm trying to run dust3d on Raspberry Pi 5 (aarch64), Raspberry Pi OS "bookworm".

Steps to build:

sudo apt install qmake6 qt6-base-dev libqt6svg6 libqt6svgwidgets6 qt6-svg-dev
cd dust3d/application
qmake6 CONFIG+=debug
make -j4

Running it in gdb results in the following crash:

Starting program: dust3d

Thanks for developing this cool 3d modeling program. I'm unfortunately not able to debug this further myself for now.
