- * Simple test of GL_EXT_blend_minmax functionality.  Four squares are drawn
- * with different blending modes, but all should be rendered with the same
- * final color.
+ * \file bug_3101.c
+ *
+ * Simple regression test for bug #3101.  Attempt to draw a single square.
+ * After emiting the first vertex, call \c glEdgeFlag to change the vertex
+ * format.  If the bug still exists, this will cause a segfault.
