<pre>I'm trying to get some unit tests from Chromium to work on Mesa.
It's using their dri backend.
It crash in the eglSwapBuffers() call, it's pretty simple to reproduce, just
call eglSwapBuffers() twice.
This only works if you call glClear() before doing eglSwapBuffers().
Here is the backtrace :
Program received signal SIGSEGV, Segmentation fault.
