Not that this is a useful construct, but it happens in some programs and did not crash before. http://www.opengl.org/documentation/specs/man_pages/hardcopy/GL/html/gl/begin.html says "Lines, triangles, quadrilaterals, and polygons that are incompletely specified are not drawn." The attached test program demonstrates the crash (it is based on the example in http://glprogramming.com/red/chapter01.html :) ) Reply at: https://bugs.launchpad.net/mesa/+bug/346072/comments/14 ------------------------------------------------------------------------ On 2009-08-24T11:45:13+00:00 Brian-paul wrote: Fixed with commit b9b04872d526ed7955f647542399e110ace0325c.
