Comment(by murble):
I can reproduce this bug on demand.
I have a network with 2 independent gateways to the internet.
Running the causing some tor traffic then switching gateways
and back again on the host
for instance
ip route change default 10.23.23.1
# wait some time
ip route change default 10.23.23.254
causes:
Feb 13 23:08:41.568 [Warning] circuit_package_relay_cell(): Bug: outgoing
relay cell has n_chan==NULL. Dropping.
which a few seconds later results in:
Feb 13 23:08:51.445 [Error] connection_ap_expire_beginning(): Bug:
src/or/connection_edge.c:649: connection_ap_expire_beginning: Assertion
circ->purpose == CIRCUIT_PURPOSE_C_GENERAL failed; aborting.
