I did little more digging into the issue

If I compile and link following sample on Linux dynamically using following command
g++ -c -I. -I/usr/local/include/boost-1_38 -I/usr/include testprogramoptions.cpp -o testprogramoptions.o

g++ testprogramoptions.o -static-libgcc  -L/u/neetug/Projects/performance/perfstat_cluster/lib -lboost_program_options-gcc41-mt -lpthread -o testprogramoptions

[root_at_perf-tools-7 src]# ./testprogramoptions  --o
ERROR unknown option o
ERROR Error while parsing CLI options Exiting

Here "--o" is unknown option
=======================================================================

If I compile and link following sample on Linux statically using following command
g++ -c -I. -I/usr/local/include/boost-1_38 -I/usr/include testprogramoptions.cpp -o testprogramoptions.o

g++ testprogramoptions.o -static-libgcc 
-Wl,-Bstatic -L/u/neetug/Projects/performance/perfstat_cluster/lib
-lboost_program_options-gcc41-mt -lpthread -o testprogramoptions

[root_at_perf-tools-7 src]# ./testprogramoptions  --o
Aborted

Here "--o" is unknown option
========================================================================
I am not sure why the behavior is different with different linking option why I am not getting exception for static linking.

Really appreciate any help in this issue. 

Here in the test program

#include <iostream>
#include <boost/program_options.hpp>
namespace boostOptions = boost::program_options;
using namespace std;

int main(int argCount, char* argList[])
{
        try {

                boostOptions::options_description commonOpt("Options (common)");
                commonOpt.add_options()
                        ("help,h", "Produce help message.")
                        ("version,v", "Prints perfstat version, and supported ONTAP versions.")
                ;

                boostOptions::options_description runModeOpt("Options ('run' mode)");
                runModeOpt.add_options()
                        ("clusterinfo", boostOptions::value<string>(), "cluster IP.")
                        ("sample-interval", boostOptions::value<int>(), "Specifies statit/sysstat frequency")
                ;

                boostOptions::positional_options_description posOption;
                posOption.add("clusterinfo", -1);

                boostOptions::options_description allOptDesc("Allowed options :");
                allOptDesc.add(commonOpt).add(runModeOpt);

                boostOptions::variables_map varMap;
                boostOptions::store(boostOptions::command_line_parser(argCount, argList).
                  options(allOptDesc).positional(posOption).run(), varMap);
                boostOptions::notify(varMap);

        }
        catch(std::exception &e)
        {
                cout << "ERROR " <<  e.what() << "\n";
                cout << "ERROR " << "Error while parsing CLI options Exiting" << "\n";
                exit(0);
        }
        catch(...)
        {
                 cout << "ERROR 1 " << "\n";
                cout << "ERROR 1 " << "Error while parsing CLI options Exiting" << "\n";
                exit(0);
        }
}

Subject: program option library segfaults for exception

Sorry for the duplicate post, I think my message posted under different conversation.

Hi,

I have application that is using boost program option
library. If I provide unknown option via CLI it should throw exception.
The library is statically linked on windows and Linux environment. It works fine on windows platform I do get exception for
unknown CLI option. On Linux platform I get "segfault" in place of
exception for unknown CLI option.

It is s a multi-threaded
application and it also uses boost thread library. Application does
throw exception on Linux also if I link dynamically. 

I am using following flags to link the library statically:

LDFLAGS=
-fexceptions -static-libgcc -Wl,-static -L/usr/lib
-lboost_program_options-gcc41-mt -lboost_filesystem-gcc41-mt
-lboost_thread-gcc41-mt -lboost_system-gcc41-mt -lnet7ssh -lbotan -ltar
-lz -lrt -lpthread

I am using following version of gcc:
# g++ --version
g++ (GCC) 4.1.1
Copyright (C) 2006 Free Software Foundation, Inc.
This is free software; see the source for copying conditions.  There is NO
