I don't believe it have something to do with Boost.Test per say.

Yes.

Here are all the places where syste error may've come from:

execution_monitor.ipp(532):    BOOST_TEST_SYS_ASSERT( ::sigaction( m_sig , 
sigaction_ptr(), &m_new_action ) != -1 );
execution_monitor.ipp(542):    BOOST_TEST_SYS_ASSERT( sigemptyset( 
&m_new_action.sa_mask ) != -1 );
execution_monitor.ipp(549):    BOOST_TEST_SYS_ASSERT( ::sigaction( m_sig, 
&m_new_action, &m_old_action ) != -1 );
execution_monitor.ipp(642):        BOOST_TEST_SYS_ASSERT( ::sigaltstack( 0, 
&sigstk ) != -1 );
execution_monitor.ipp(648):            BOOST_TEST_SYS_ASSERT( 
::sigaltstack( &sigstk, 0 ) != -1 );
execution_monitor.ipp(667):    BOOST_TEST_SYS_ASSERT( ::sigaltstack( 
&sigstk, 0 ) != -1 );
execution_monitor.ipp(696):    BOOST_TEST_SYS_ASSERT( ::signal( sig, 
SIG_DFL ) != SIG_ERR );

What you can do is to try catch the exception in your code and report it 
yourself. This may at least show some information. I guess I should also 
include failed expression text. It's not there yet.
