[asterisk-bugs] [JIRA] (ASTERISK-22757) segfault in res_clialiases.so on reload

[Corey Farrell (JIRA)]

    [ https://issues.asterisk.org/jira/browse/ASTERISK-22757?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=211277#comment-211277 ] 

Corey Farrell commented on ASTERISK-22757:
------------------------------------------

Steps to cause segfault (I think on any current version, not just 11.x):
1) Start asterisk with cli_aliases.conf having reload=module reload
2) touch cli_aliases.conf (change timestamp to force reload)
3) From cli run 'reload'.  You will see warnings from cli.c about the reload command.
4) Press tab in asterisk CLI for command completion.  Segfault.

I know this isn't exactly how the segfault happened for Gareth, but since backtrace.txt shows the 'reload' alias in use I suspect it could be the same root cause (failure to remove the reload command alias).

> I performed a reload and asterisk crashed. There were a couple of new dynamic features changed and quite a lot of dialplan changes.
