Gordon Sim created DISPATCH-928:
-----------------------------------
Summary: calling map_destination for 'undefined' address causes
segfault
Key: DISPATCH-928
URL: https://issues.apache.org/jira/browse/DISPATCH-928
Project: Qpid Dispatch
Issue Type: Bug
Reporter: Gordon Sim
If qdr_map_destination_CT is called for an address that has not been defined on
a router that has the default distribution set to 'undefined', qdr_address_CT
(line 578 at present) returns null. However there is no check for this and the
address is used to get a hash_handle which causes a segfault.
Under valgrind you see:
