I set a bunch of breakpoints to see where the stack got corrupted, i.e.
where backtrace started printing question marks.  It turned out the code
was using an XAnyEvent (size 20) in place of an XEvent (size 96); thus
the overrun.

Mostly harmless as far as I can tell, but patches are always welcome. ;)
