Done: Test passes both with and without the patch, both under gcc compiled asterisk as well as clang compiled asterisk: Result PASS. SideNote1: All this work i have been doing was to make asterisk compilable clang, so it should be able to run these tests as well, right. With all the submitted patches in place it compiles and runs in dev-mode as well. SideNote2: Because of the discovered error in this function i guess the test should / would have to be updated for this particular case to prevent future regressions. - Diederik ----------------------------------------------------------- This is an automatically generated e-mail.
