I was citing the one case which did zero terminate.

When I say crash it should be "locks up", which means it doesn't redraw or
allow changing client. However, it's not using a noticeable amount of CPU.
Dunno about the backtrace: I've set -g in the makefile and removed the strip and
attaching gdb in a VT gives something that doesn't complain, but looks a bit
suspicious so maybe gdb is misreading the executable.
Copying manually important bits, backtrace is

0 poll()
1 XProcessInternalConnection
2 _XRead
3 _XReply
4 _XSync
5 event.c:317 drawstatus (e=Variable not available)
6 main.c:318 handler[ev.type].....

where p ev gives many screens of stuff with ev.type=28

One definite thing is if I comment out the sel->name printing in drawstatus
it doesn't lock-up, otherwise it reproducibly does here.

I'll try getting the tip and seeing if it works next.

cheers, dave tweed
