             Summary: STACK_PEEK function with no arguments causes crash/core dump
                 Key: ASTERISK-23220
                 URL: https://issues.asterisk.org/jira/browse/ASTERISK-23220
             Project: Asterisk
          Issue Type: Bug
      Security Level: None
          Components: Applications/app_stack
    Affects Versions: 11.4.0
         Environment: Centos 6.4, amd64
            Reporter: James Sharp


When setting up to use STACK_PEEK, I inadvertently left the arguments out of the dialplan.  When the dialplan reached this point in execution, Asterisk crashed with a core.  I realize that it was my error in the configuration, but I feel the system should flag an error rather than crash in a blaze of core dumps.  If this is a true bug, I can rebuild the system with DONT_OPTIMIZE to get a full backtrack.

The offending dialplan entry is this:

exten => 9998,1,Set(FOO=${STACK_PEEK()})
