Resolution: Fixed
> 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
> Affects Versions: 1.0.0
> Reporter: Gordon Sim
> Assignee: Ganesh Murthy
> Priority: Major
> Fix For: 1.1.0
>
>
> 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:
> {noformat}
> ==10232== Invalid write of size 8
> ==10232== at 0x4E67501: qd_hash_internal_insert (hash.c:156)
> ==10232== by 0x4E6756B: qd_hash_insert (hash.c:168)
> ==10232== by 0x4E91644: qdr_map_destination_CT (route_tables.c:579)
> ==10232== by 0x4E8F80D: router_core_thread (router_core_thread.c:83)
> ==10232== by 0x550F739: start_thread (in /usr/lib64/libpthread-2.24.so)
> ==10232== by 0x607AE7E: clone (in /usr/lib64/libc-2.24.so)
> ==10232== Address 0x98 is not stack'd, malloc'd or (recently) free'd
