    Issue:

     

    We're running Web Agent on Apache, this one crashes and report the
    error :

    [Tue Mar 27 15:57:33.724447 2018] [authz_core:debug] [pid 19651:tid

    terminate called after throwing an instance of 'std::logic_error'
    what(): basic_string::_S_construct null not valid

    How can we solve this ?

     

    Environment:

     

    Web Agent 12.52SP1CR08 64bit on Apache 2.4.6 64bit on RedHat 7.2;

     

    Cause:

     

    The code was allowing a null pointer exception where the code is
    trying to clear a list which was empty. The fix will be available to
    Web Agent 12.52SP1CR09
