Ken Giusti commented on QPID-2045:
----------------------------------
Potential cause:
The method Link::destroy() removes bridges from the "active" vector member, but
does not invoke the bridge's ::closed() method.
Other Link class methods that clean the active vector - Link::closed() and
Link::cancel() - manually invoke the bridge's ::closed() method for every
bridge that is removed from the active list.
I tried adding a call to the bridge's closed() method from within
Link::destroy() active vector cleanup - no crash. This seems correct in the
fact that the bridge's create() method (which is cancelled by the bridge's
closed() method) is invoked by Link when the bridge is added to the active list.
Thoughts?

> While experimenting with the Federation tests, I managed to cause a crash in

> "bridge.close()" on one of the bridges. This results in a broker crash. I
