Maybe that is the reason that the current buffer is being killed under
our feet, I don't know.
Is the GDB session still alive? If so, could you show what the
following displays?
(gdb) p XWINDOW(selected_window)->contents
(gdb) xtype
If "xtype" says it's a buffer, please type:
(gdb) xbuffer
and tell what that shows.

I don't really have an idea where to set such a breakpoint, since I
don't understand how is this buffer killed. I'm guessing you have
some elaborate hooks set up that succeed in killing the current buffer
while redisplay runs or something, that's how such problems are
usually born.
