Which version of vnc is this? I can take a look at line 298 of selection.c to see what it's doing. My guess, however, is that it's a bug in vnc that is triggered by the new clipboard support. It looks like it's crashing while reading the X11 clipboard or primary selection. On Jan 6, 2009, at 07:07, Kyle Lucke wrote:

I upgraded to 2.3.2.1 on my dual-display Macbook pro at 10.5.6 over the weekend. I've returned to work after the break, and have had 3 X11 vncviewer app crashes today with a "bus error." This had never happened with 2.3.1.

Ideas for further debug?

Could you please send me the stack trace of the crash

Here it is:
