I strongly suspect that the problem is the LD_PRELOAD will interfere with a
apitrace, as apitrace too, uses LD_PRELOAD to do its thing. I think think
this will ever work.

If you want to trace Mesa, I suggest you build the pure XLIB libGL.so sw
rasterizer, and then use LD_LIBRARY_PATH=... . This works -- I use it very
often.
