[sr-dev] git:sr_3.0: tm: fake_req dst_uri and ruri copy fix

Module: sip-router Branch: sr_3.0 Commit: 583d213cb617e767f5895de18168d7516e51e5e6 URL: http://git.sip-router.org/cgi-bin/gitweb.cgi/sip-router/?a=commit;h=583d213… Author: Andrei Pelinescu-Onciul <andrei(a)iptel.org> Committer: Andrei Pelinescu-Onciul <andrei(a)iptel.org> Date: Wed Feb 17 20:40:46 2010 +0100 tm: fake_req dst_uri and ruri copy fix If the uris have 0 len but no 0 value (possible at least for a manually set dst_uri), set the corresponding fake_req uri to 0, thus avoiding a potentially disastrous free in free_faked_req().
