This should be a circle...

The error ocurrs on Windows 7 and on Linux with Mesa softpipe and llvm.

There seem to be random lines between non-adjacent points in the line loop.
When switching to GL_LINE_STRIP, the error disappears.

Attached you find a screenshot and a Qt example program (see glwidget.cpp for
the minimal GL_LINE_LOOP code).

The bug only happens when there are more than about 512 lines and there are
more errors the more lines are in the loop (as seen in the screenshot).</pre>
