<pre>I built a glxgears with debug symbols and used gdb, I discovered pressing 'a'
several times (to pause and restart animation) can effectively trigger the
halt, and the stack trace when it is halted is always as below (sorry I used
heavily optimized and stripped binaries, I am too lazy to build them myself):

line 183 at draw() is:
glClear(GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT);
I guess it has something to do with dri3.</pre>
