Comment (by nickm):

 Interesting!

 The failing line seems to be:
 {{{
       cmux->policy->free_circ_data(cmux,
                                    cmux->policy_data,
                                    circ,
                                    hashent->muxinfo.policy_data);
 }}}

 The most useful stuff would be the contents of cmux and circ at level 5,
 from that crash.  So, in gdb:
 {{{
  up 5
  p *cmux
  p *circ
  p *cmux->policy
  p *cmux->policy_data
  p hashent
  p *hashent
 }}}
