Hi, I found an issue with testing my Spirit app, but after some 
investigation it seems to be more of an issue with Boost Test.

The error message is as follows:

Running 2 test cases...

*** No errors detected
spirit2(53940) malloc: *** error for object 0x30001013006d0: pointer 
being freed was not allocated
*** set a breakpoint in malloc_error_break to debug

As the error message suggests I set a breakpoint and got this stack trace:

(gdb) bt
#0  0x00007fff88021b91 in malloc_error_break ()
#1  0x00007fff87f4b083 in free ()

#6  0x00007fff87f5718c in exit ()
#7  0x000000010000b7bb in start () at unit_test_parameters.ipp:172

Complete code is below. It is compiled on MacOS 10.6.1 with the default 
gcc 4.2 compiler against boost 1.40 (installed via MacPorts).

I note that if the problem disappears when the two 
BOOST_AUTO_TEST_SUITE lines are removed. Also it disappears when one of 
the test cases is commented out.

Any help appreciated.

#define BOOST_TEST_MODULE spirit test
#include <boost/test/included/unit_test.hpp>

#include <boost/spirit/include/qi.hpp>

namespace qi = boost::spirit::qi;

template <typename Iterator>
struct MyGrammar : public qi::grammar<Iterator>
{
    MyGrammar()
        : MyGrammar::base_type(sp)
    {
        using boost::spirit::char_;

        sp = char_(' ');
    }

    qi::rule<Iterator> sp;
};

    MyGrammar<std::string::const_iterator> parser;
