Segmentation fault in sun4i-drm_dri.so

Hello,

I'm trying to get OpenGL working on the Orange PI PC board with the Mali400 graphics chip and Armbian/Debian Sid. Everything looks pretty good, xserver runs in fullHD without problem. Glxinfo shows correct informations. But everytime, I run OpenGL application, for example glxgears or supertuxkart, I get segmentation fault.

$ gdb glxgears

Starting program: /usr/bin/glxgears 
[Thread debugging using libthread_db enabled]
Using host libthread_db library "/lib/arm-linux-gnueabihf/libthread_db.so.1".

Program received signal SIGSEGV, Segmentation fault.

$ glxinfo

OpenGL vendor string: lima
OpenGL renderer string: Mali400
OpenGL version string: 2.1 Mesa 20.0.4

Video memory: 0MB looks little weird.

Can you help me debug this problem, or should I ask for help somewhere else?
