I did run the X server that crashes (the guest one) under GDB, as outlined on https://wiki.ubuntu.com/X/Backtracing

I save output to file (attached) and did say backtrace full. So here it is.

Looks like it occurs in drm_intel_bo_unreference, which, sadly, likely suggests a memory corruption elsewhere. drm_intel_bo_unreference is called by gen4_render_state_cleanup.
