back trace of hang

DRI3 and an application started with xinit causes the glut draw function to hang if the following three functions are used together (see backtrace.txt and example app).

glutInitWindowPosition
glutFullScreen
glDrawBuffer(GL_FRONT)

Commenting out any one of these 3 functions allows the application to run correctly. 

Forcing DRI2 allows the application to work correctly with those 3 function calls intact.

Doesn't look driver specific, reassigning to Mesa core.
