apitrace is being injected into apitrace...

This can only happen if you have stuff you shouldn't have on LD_PRELOAD and
LD_LIBRARY_PATH variables...  :-/

Please start from a clean terminal.  Don't do anything other than I described. 
In particular don't set LD_PRELOAD, and only set LD_LIBRARY_PATH=$PWD.

Honestly it's better not to fiddle with LD_PRELOAD directly yourself at all. 
It just makes everything unnecesarily harder.  Just let the `apitrace trace`
command do it.


I repeat: 

- the right way of loading libGL.so is to set
LD_LIBRARY_PATH=/path/to/where/libGL.so.1/lives/

- the right way of tracing is to `apitrace trace myapp`

- and the right way of doing both is to

  export LD_LIBRARY_PATH=/path/to/where/libGL.so.1/lives/
  apitrace trace myapp


(Also note, the right name for libGL is not libGL.so as you had in the tarball.
 It needs to be libGL.so.1.  I suspect that this mismatch is what lead you to
resort to LD_PRELOAD to start with.  But if the name is libGL.so.1 that should
never be necessary.)
