lib32-mesa Gallium3D drivers SIGSEGV with old Linux native games
I have tried to run 2 old Linux native games on modern and fully updated ArchLinux x86_64 using the multilib support.
- Heavy Gear II - Loki Entertainment
- SHOGO Mobile Armor Division - Hyperion Entertainment
They are targets for 32-bit Linux x86, gtk1.2, glib1.2 and early SDL and OpenAL. They don't have source ports. After installed and symlink'ed (old->new) libs, here's the results:
- i915, i965 DRI drivers OK
- nvidia-390xx dirvers OK
- Gallium3D drivers SIGSEGV (r600, nouveau, radeonsi, virgl, swrst)

The SIGSEGV trapped during C++ static initialization. I had triage the issue and found the following simple one-liner patch fixes the issue for builds with b_ndebug=true.

Unfortunately, I am not able to provide a simple test case without requiring the whole game. Running glxgears, glmark2, quake2 and avp source ports are all fine.
