With boost 1.44.0 (the same happens with 1.43) the following test causes a crash in framework.ipp:388 with a dereference of a NULL pointer. The test_unit* res returns NULL from s_frk_impl().m_test_units[id] where id is 1. id is equal to 1 because when unit_test::framework::run is ran, id is INV_TEST_UNIT_ID is passed to it. Then in framework.ipp:399 if id == INV_TEST_UNIT_ID id is assigned the value in master_test_suite().p_id which is 1. I've verified that when master_test_suite is constructed it assigns INV_TEST_UNIT_ID to p_id, so I'm lost why this is 1 here. Then, back in framework.ipp:386 s_frk_impl().m_test_units there's only one element in the map and the id is 65535 and not one. -- test.cpp -- #define BOOST_TEST_MODULE parse_empty_import_documents #include BOOST_AUTO_TEST_CASE (parse_empty_import_documents) { } -- test.cpp -- Any help would be appreciated. -- Felipe Magno de Almeida
