Bug#1121993: f3d: Crash when opening OBJ file on MNT Reform 2 (segmentation violation)

[Ælla Chiana Arson Bobbie Moskopp]

Package: f3d

I do have a working OpenGL implementation on the MNT Reform 2.
Several  other 3D applications work fine with my OpenGL setup:

• Minetest/Luanti 5.10 (without shaders, for performance)
• castle-model-viewer 5.2.0 (I use it instead of f3d now)
• Nexuiz 2.5.2 (have to set MESA_GL_VERSION_OVERRIDE=3.2,
as otherwise it crashes at startup, due to an engine bug)

glxgears has untexturized gears (a somewhat recent regression)
but runs with a constant 51.363 fps, or about 37.5 fps as soon
as I force software rendering. The only other app that has the
“untextured” bug I have seen is neverball 1.6.0, but it can do
run fine on this machine (it did with previous Mesa versions).

In case it matters, I am using the Wayland compositor “sway”,
Mesa version is “25.2.8-2”, GPU is “Vivante GC7000 rev 6214”.
