OpenSAML user discussion

["Cameron Morris" <>]

This is a strange one.  In my code I core dump when parsing an assertion.

 

At the bottom of this message is the code, nothing complex.  It just initializes saml and constructs a SAMLAssertion.  Attached is the assertion I'm parsing.  The strange part is that I can successfully parse and verify this assertion with the signtest executible - so I must be doing something silly.

 

Here is the stack trace:

#0  0x4012d102 in (anonymous namespace)::g_config () from /opt/shibboleth/lib/libsaml.so.4

It crashes on the line 192 of SAMLAssertion::fromDOM:

 

192                 SAMLInternalConfig& conf=dynamic_cast<SAMLInternalConfig&>(SAMLConfig::getConfig());

 

Oh and here are my system details:

gcc=3.3.3

OpenSAML=version 1.0 tarball

Kernel=2.6

OS=SuSE Linux 9.1

 

 

Thanks,

Code:

 

#include <iostream>

#include <saml/saml.h>

 

using namespace std;

using namespace saml;

 

int main (int argc, char *argv[])

{            

    unsigned char *cert;

    long certLen;

 

    //saml setup:

    int rc;

 

    //Configure SAML libraries

    SAMLConfig& samlConfig = SAMLConfig::getConfig();

    samlConfig.schema_dir="/home/cmorris/work/build/opensaml/etc/opensaml";

 

    if ( !samlConfig.init() )

    {

        cerr << "An error occured initializing the SAML environment" << endl;    

        return false;

    }

 

    ifstream in;

    in.open("../test/sa.xml", ios::in);

    SAMLAssertion *sert = new SAMLAssertion(in);

}
