Now I can build the extra modules under Windows and it seems to
work at the first glance.

Hi Xiaofan,

The good news (or bad news depending on your perspective), is that I can 
still duplicate the segv on my other system (my non-development system). 
  I'll take a look at the problem on this system.

The same problem happens under FC5.

As far as I can tell now, the issue appears to lie with the way I'm 
using GTK. As you may know, gpsim's HD44780 module renders the LCD in 
it's own stand alone window. However, gpsim's SED1520 module renders the 
LCD in the Bread Board window. There appears to be some weird issue with 
constructing the gui stuff outside of gpsim's normal environment and 
then using it within gpsim's environment.

I'll try to pin point if this is the problem by creating a special 
version of the SED1520 module that renders the display in a separate window.

Under my newly installed Ubuntu 6.06 AMD64 64-bit, the graphic
LCD module is working.
