[asterisk-bugs] [JIRA] (ASTERISK-24869) Asterisk segfaults on DAHDI attended transfer

[viniciusfontes (JIRA)]

    [ https://issues.asterisk.org/jira/browse/ASTERISK-24869?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=225363#comment-225363 ] 

viniciusfontes commented on ASTERISK-24869:
-------------------------------------------

The last two lines in the log are as follows:

[Mar 12 10:43:39] VERBOSE[28577][C-00000227] sig_analog.c: TRANSFERRING DAHDI/38-1 to DAHDI/38-2
[Mar 12 10:43:39] VERBOSE[28566][C-00000227] res_musiconhold.c: Stopped music on hold on IAX2/dundi-ramais-11400

After that, Asterisk crashed with a segmentation fault.

It seems like the user is trying to make an attended transfer to its own extension, which is odd. However, I believe that should not make Asterisk crash.

> OS detail: Debian 7.8 (Linux 3.2.0-4-amd64 #1 SMP Debian 3.2.65-1+deb7u2 x86_64 unknown unknown GNU/Linux)
> I'll attach the relevant part of /var/log/asterisk/messages and the backtraces.
