AFAIK BOOST_FOREACH is a macro. Therefore it is expanded by pre-processor
into the real code. Can you debug into macros with g++/gdb anyway? MSVC
supports that, but what about g++/gdb?

There might be some workarounds, like temorary modifying the BOOST_FOREACH
code and placing a debug break compiler intrinsic call into it. I think than
you might be able to stop the debugger inside, but not sure what is shown
than.

Good Luck,
