  26  * Test aims to reproduce SIGSEGV on i965 appearing on certain
  27  * sequences of switching glx and egl contexts. Particular sequence
  28  * that leads to crash:
  29  *
  30  * 1. Make glx context current
  31  * 2. Make egl context current
  32  * 3. Drop glx context
  33  * 4. Make egl context current
  34  *
  35  * In order to reproduce the crash you also need to export the loader:
  36  * export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:$PATH_TO_MESA_BUILD/lib
