I'm using Archlinux x86_64, tmux compiled from SVN, rev. 2860. Recently
I updated my system with new kernel, 3.5.3, and libevent, 2.0.20. I
rebooted after update and started tmux, after I pressed `Esc' tmux
'crashed', I only see 'lose connection'. The next 'tmux attach' gives
message 'no session', simple 'tmux' is ended with message 'detach'.

Does it dump core (assuming ulimit is set correctly?)  If so, get a stack trace.

Attaching the backtrace.

Basically,
