  25  * Test related to fd.o bug 31590 involving glEvalCoord inside a display list
  26  * when running the glut molehill test.
  27  * The mesa-demos redbook/bezcurve.c test (when hacked to use a display list)
  28  * also demonstrated the problem.  This program is based on the later program.
  29  *
  30  * We test for two things:
  31  *  1. an unexpected GL_INVALID_OPERATION error
  32  *  2. a segfault/crash during display list compilation
