Boost 1.37.0, Linux, x86_64, gcc 4.1:
Valgrind 3.3.1 complains when running this simple test:
#define BOOST_TEST_MAIN
#include
BOOST_AUTO_TEST_CASE( test1 )
{
BOOST_CHECK( 1 == 1 );
}
The valgrind messages:

I was not able to figure out what valgrind is really complaining about.
The internal map of test units holds two entries. One corresponds to my BOOST_AUTO_TEST_CASE call (id=1), the other one seems to be used internally (id=65536).
Both are properly erased in deregister_test_unit() which is called by ~test_unit().
Maybe someone with a little bit more insight into Boost.Test is willing to look at this.
