Hi Gennadiy, yesterday I noticed that valgrind reports an error for the boost test framework. This is for a file with a single and empty BOOST_AUTO_TEST_CASE: ==3513== Invalid read of size 4 ==3513== at 0x40936E0: boost::unit_test::framework_impl::clear() (framework.ipp:133) ==3513== by 0x409383C: boost::unit_test::framework_impl::~framework_impl() (framework.ipp:122) ==3513== by 0x42466C8: exit (in /lib/libc-2.8.so) ==3513== by 0x422F5CC: (below main) (in /lib/libc-2.8.so) ==3513== Address 0x4375ba4 is 20 bytes inside a block of size 24 free'd ==3513== at 0x402272A: operator delete(void*) (in /usr/lib/valgrind/x86-linux/vgpreload_memcheck.so) ==3513== by 0x409161C: __gnu_cxx::new_allocator<std::_Rb_tree_node<std::pair<unsigned long const, boost::unit_test::test_unit*> >
