Hello Performers,

I started using the following piece of code so that the channel has
a non-symmetrical frustum. It works fine with OpenGL, however, the
Iris gl version causes a segmentation fault when chan->apply() is
called. Has anyone else had problems using pfChannel::makePersp()
and pfChannel::apply() compiled with IRISGL?

    chan->makePersp( near*pfTan(fov_left),
                     near*pfTan(fov_right),
                     near*pfTan(fov_bottom),
                     near*pfTan(fov_top) );
    chan->apply();
