Routing service crash when trying to dynamically create a new session


when I try to create a new session via rtirssh, the routing service is crashing. It does not happen when there's no publisher in the subsribing domain.

A small test can be done with two rti shapesdemo instances - one in domain 0 and one in 1. The routing service can be started with the default config (rtiroutingservice -cfgName default) which routes traffic from domain 0 to domain 1.

With rtirssh I can retrieve some information via 'get default' and can also remove the session with 'delete default DefaultDomainRoute::DefaultSession'

After this when I try to readd the session (and the shapes demo in domain 0 is publishing) I get a crash with this bt:

Thread 9 "rtiroutingservi" received signal SIGSEGV, Segmentation fault.

When there's no publisher in domain 0, the route is created without a crash...

create command:

create default session DefaultDomainRoute str://"<session name="DefaultSession"><auto_topic_route name="RouteAll"><input participant="1"><deny_topic_name_filter>rti/*</deny_topic_name_filter><creation_mode>ON_DOMAIN_AND_ROUTE_MATCH</creation_mode></input><output participant="2"><deny_topic_name_filter>rti/*</deny_topic_name_filter><creation_mode>ON_DOMAIN_AND_ROUTE_MATCH</creation_mode></output></auto_topic_route></session>"

Is it not allowed to create a new session when there are already publishers?
