Thank you for the report. Unfortunately, 3D pass-through in Linux guests is currently mainly user-supported<1>. We might or might not find time to look at this (though we probably should not, based on available developers and current work load); however if you can identify the problem yourself chances are higher that it will get fixed. The easiest way would probably start with building the Additions yourself<2>, if possible in the affected guest, for ease of debugging. I would not try to build the installer; instead I would just replace the libraries you need to debug with the versions you built yourself to get debugging information (there is a small chance that would go wrong, but I think it really is small).

I got the debug build of the additions working: ​https://forums.virtualbox.org/viewtopic.php?f=10&t=80202

As I see, it is not a fault of the additions:

Program received signal SIGSEGV, Segmentation fault.
0x00007fffc06e8d2f in crPackColor4ubv (v=0xc <error: Cannot access memory at address 0xc>)
    at /home/k0/virtualboxdebug/vbox/out/linux.amd64/debug/obj/VBoxOGLgen/packer.c:1911
1911		WRITE_DATA(0, GLubyte, v[0]);

as v is supplied by ogre (you even check for a NULL Pointer). So I assume that ogre or what's the stack up is at fault? The backtrace is as gdb_addtions_debug.txt attached. If this assumption is correct and segfault is in this case the expected behaviour, then please close this bug ticket.
