No, that's not a good idea, IMO: this place will hit the breakpoint
all the time.  xdisp.c:6922 is in the call-stack because that's where
get_next_display_element calls another function, which caused stack
overflow due to what seems to be infinite recursion.

Not yet, let's first see what's causing this with the session you
already have captured in the debugger.

Thanks!
