     Type:  Bugs                                     |      Status:  new    
Milestone:  Boost 1.47.0                             |   Component:  test   
  Version:  Boost 1.46.1                             |    Severity:  Problem
 Keywords:  test unit_test memory leak               |  
-----------------------------------------------------+----------------------
 There is memory leak in the
 boost::unit_test::ut_detail::generate_test_case_4_type::operator() which
 is used by boost::unit_test::ut_detail::template_test_case_gen
 which in its turn is used by BOOST_AUTO_TEST_CASE_TEMPLATE

 The problematic code is provided below. The test_case created here never
 gets deleted.
 {{{
 template<typename TestType>
 void        operator()( mpl::identity<TestType> )
 {
   ...
   m_holder.m_test_cases.push_back(
      new test_case( full_name,
 test_case_template_invoker<TestCaseTemplate,TestType>() ) );
 }
 }}}

 Below is the code that can be used to reproduce the issue:
 {{{
 #define BOOST_TEST_MAIN
 #include <boost/test/auto_unit_test.hpp>
 #include <boost/test/test_tools.hpp>
 #include <boost/test/test_case_template.hpp>
 #include <boost/mpl/list.hpp>

 BOOST_AUTO_TEST_SUITE( TestMemLeak )

 BOOST_AUTO_TEST_CASE_TEMPLATE( TestCase, Type, boost::mpl::list<int> )
 {
 }

 BOOST_AUTO_TEST_SUITE_END()
 }}}

 '''Note:''' This leak is detected only when application is linked with C
 runtime statically.
 Configured test application can be found in the attachment

 Execution output:
 {{{
 Running 1 test case...

 *** No errors detected
