While trying to reproduce a problem with the xlib backend on my newly installed SuSE 10.1 system, I found that menus get only partially displayed, also the knob in horizontal sliders was missing. With this few hints I set off to drag down the bug behind it. It took my quite some time, but now I think I found it. The affine transform used to compute the state transformation suddenly had a NaN component as TY. How could this ever happen? I put in a few NSLog statements into [NSAffineTransform scaleXBy:YBy:] and the problem was gone.
For me this proves that there is a gcc problem (gcc (GCC) 4.1.0 (SUSE Linux)), but how to deal with it? The simplest thing is surely to switch off some optimisation for this file. As far as I remember, there is even a switch for this in GNUmake. The danger is that the same problem may show up in other places as well. How could we prepare for that? What I don't understand is why this problem doesn't show up for other backend and why I am the first one affected? Many of you should already use gcc 4.1, what is so special about the SuSE version? Perhaps nobody ever uses the xlib backend any more? Could those using gcc 4.1 on a 32 bit Intel machine try at least once?
