Hello all,

First of all:
I'm building an application and with that I use Boost test for unit testing. This helped
me already to fix some obscure bugs. (I am very happy with boost test)

I have the Master suite test setup in one file and the normal test suites each in one
file. This worked very well. Now I have the following test suite which gives me a
segmentation fault and I have no idea why:

BOOST_AUTO_TEST_SUITE(ProgramOptions)

BOOST_AUTO_TEST_CASE(ProgramOptions_Valid_Options) {

    // Output
    boost::test_tools::output_test_stream output("misc/ProgramOptions_01.output", true);

    // Save output buffer
    std::streambuf *strmbuffer;
    strmbuffer = std::cout.rdbuf();

    // Redirect the output.
    std::cout.rdbuf(output.rdbuf());

    // Redirect output stream so we can do some checks.
    printSomething();
    BOOST_REQUIRE(output.match_pattern());

    // Now lets process some arguments.
    printSomething();
    BOOST_REQUIRE(output.match_pattern());

    // Restore output buffer
    std::cout.rdbuf(strmbuffer);
}

BOOST_AUTO_TEST_SUITE_END()

The function that gets tested:
void printSomething() {
    std::cout << "Test output" << std::endl;
}

If I put the same content 'Test output' in the ProgramOptions_01.output file then everything
is fine and executes ok. When putting different content in that file it goes wrong.

I have also a gdb backtrace if that is interesting:
(gdb) r
Starting program: /home/matthijs/Projects/cppcms/trunk/cmsapp_test

Hopefully someone with some insight in boost.test can help me
out here...
