----------------------------------------

             Summary: After  putting autoload to true in modules.conf I get a segmentation fault.
                 Key: ASTERISK-21823
                 URL: https://issues.asterisk.org/jira/browse/ASTERISK-21823
             Project: Asterisk
          Issue Type: Bug
      Security Level: None
            Reporter: Dolf Schimmel


I performed the following steps on an Ubuntu 12.04 machine:

curl http://downloads.asterisk.org/pub/telephony/asterisk/asterisk-11-current.tar.gz | tar -xvz -C /var/lib/puppet/src/asterisk --strip 1 
./configure
make
make install{quote}

After setting up some very minimal configuration, asterisk just works. However, the moment I set the autoload directive to 'yes' in my modules.conf I get a segementation fault while starting Asterisk.

Please let me know if there's anything else I can do to help reproduce or debug this issue. Perhaps there's a very logical explanation, but I figured a segmentation fault is not what should happen nonetheless ;)

Thanks for making an awesome product!
