Do you have any additional information in regards to how to reproduce this issue?
By: chitman (chitman) 2009-01-12 02:19:22.000-0600
I have added full backtrace in btfull.txt and info from a logfile in log.txt.
I'm waiting for crash now with debug=4 and verbose=4 for granting more informative output for you.

If you can create a repeatable case, please try this patch.
By: chitman (chitman) 2009-01-13 04:47:23.000-0600
I don't know in which case it crashes. I'm testing this patched version now and I'll tell you about results later.

I think that I too have this problem, I get this in CLI console
[Jan 13 11:18:09] ERROR: astobj2.c:116 INTERNAL_OBJ: bad magic number 0x81aea1c for 0x83af984
and asterisk restarts ...the bt results is attached.

Issue has a patch attached for testing.
By: chitman (chitman) 2009-01-14 05:19:33.000-0600
I have got the same error now. I have uploaded details about this crash in the details.txt.
By: Tilghman Lesher (tilghman) 2009-01-14 14:00:23.000-0600
Okay, it looks like memory corruption. Let's try following the instructions in doc/valgrind.txt.

Maybe results of bug 14260 can help...
By: Leif Madsen (lmadsen) 2009-01-20 14:22:29.000-0600
I have marked the issues as duplicate between here and 14260, but I'd like Corydon76 to verify if that is the case before I close one of the issues down.
By: Mark Michelson (mmichelson) 2009-01-22 18:41:27.000-0600
I can verify that this is a duplicate of 14260.
The problem is that when an attended transfer occurs, the end_bridge_callback is called for app_queue and is passed data which was previously on the stack but which since has gone out of scope. I have been working on issue 14260 and have worked out the circumstances for this bug but have not yet formulated a patch to fix the issue. I expect that I will have something ready tomorrow, though.

I have uploaded a patch which fixed the issue for me. The patch I have uploaded here is functionally equivalent to the patch uploaded for issue ASTERISK-13384. The difference is that the patch posted here is for the 1.6.0 branch of Asterisk and the patch on issue ASTERISK-13384 is for Asterisk trunk.
Please test and let me know if there are any issues with this patch.
By: Leif Madsen (lmadsen) 2009-01-28 15:29:03.000-0600
Ping! Have an ETA on testing? Thanks!
By: chitman (chitman) 2009-01-28 23:24:08.000-0600
I applied patch today and testing it now. I'll report about results later.
By: Mark Michelson (mmichelson) 2009-01-30 10:20:50.000-0600
Since the reporter of issue ASTERISK-13384 reported that this patch fixed the problem for him, I went ahead and merged the patch into Asterisk trunk, 1.6.0, and 1.6.1.
Since the code has already been merged into Asterisk, I am going to close this issue, too. If you find that this does not work, please feel free to re-open this issue and I will examine this more closely.
