Description:Setting a port number on the host declaration, such as host=1.2.3.4:123 causing asterisk to crash.

Confirmed to crash every time the peer is loaded with 1.8.7.1 using realtime and 1.8.7.2 with sip.conf.

Thank you for your bug report. In order to move your issue forward, we require a backtrace[1] from the core file produced after the crash. Also, be sure you have DONT_OPTIMIZE enabled in menuselect within the Compiler Flags section, then:

make install

After enabling, reproduce the crash, and then execute the backtrace[1] instructions. When complete, attach that file to this issue report.

I don't have a development server available to recompile this at the moment.  I'm using Digium's compiled RPMs on CentOS 5.7.

You must have some extra settings than what I'm trying, because with 1.8.7.2 I am unable to reproduce this with the information you've provided:

Okay.  I've narrowed it down by deleting one line of my sip.conf until I found which line to delete to *not* crash.

Here's a sip.conf with ONLY what's required TO cause the crash:

{code}
[general]
dynamic_exclude_static = yes

[crashme]
type=peer
host=10.12.10.2:5062

------------------------------------------------------------------------
r343851 | rmudgett | 2011-11-08 18:58:21 +0100 (Tue, 08 Nov 2011) | 14 lines

Fixed reference to incorrect variable if unknown host configured crash.

* Fixed a LOG_ERROR message referencing the config variable list v that
had previously been processed and became NULL.

* Added error return value set that was missing in an ast_append_ha()
error return path.
