[asterisk-bugs] [JIRA] (ASTERISK-27992) Adding `sends_registrations = yes` to pjsip_wizard.conf causes crash with pjsip 2.7.2

[Richard Mudgett (JIRA)]

    [ https://issues.asterisk.org/jira/browse/ASTERISK-27992?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=244346#comment-244346 ] 

Richard Mudgett commented on ASTERISK-27992:
--------------------------------------------

Yep.  I've reproduced the crash with the supplied [^pjs_wiz.conf] file.  Just uncomment the indicated line and you crash when asterisk loads.  It appears to be some combination of options that causes the crash.  As I'm not familiar with the wizard configuration method nor the code a fix is not obvious to me.

However, the sends_registrations option is used in other sections without a crash and there is a typo in the option names in that section:
{noformat}
outound_auth/username = XXXXXXXX at sip2sip.info
outound_auth/password = XXXXXXXX
{noformat}

Fixing the typo in outbound_auth also avoided the crash.

> Adding `sends_registrations = yes` to pjsip_wizard.conf and reloading causes segfault. Asterisk will not start after that. In the syslog:
