I'm currently developping a software using COCOA framework and linking with Apple implementation of gl and glu.
When I try to use the tesselator in BOUNDARIES mode, I almost always get the computer to freeze. It cannot recover unless I reboot it (under MacOS X).

It just works fine when I use the tesselator to get triangles instead of boundaries.

I've double-checked my code and it seems the problem comes from the framework. (with protected memory my code would not be able to freeze the GUI, right ?)

Can you help me ?
