[Boost-users] can't debug into BOOST_FOREACH?

Hi there, I just noticed there seems to be no way of debugging into a BOOST_FOREACH loop... Is that true? I use g++ 4.3 / gdb 6.8 here and neither would the debugger stop any any breakpoint inside such loops nor can I step into them from outside. Is this supposed to be like that? puzzled... Stephan
