nanogui: Thread: Prolem in Microwin TrueType font display

Dear all,

I have compile the microwin with multibyte patch. When I run a simple 
displaying Chinese TrueType Font example in iPAQ, I meet the Segmentation 
fault. I have try in Destop RedHat Linux and it work! I don't why the 
Segmentation fault occur in iPAQ. Could anyone tell me the reason or Have 
you meet such of this kind problem before?

Thank a lot!


Cheer,
Gary
