I've looked a tiny amount further (but don't have time to investigate further). I'm sure this will prove useful.

Hi Paul, I have found a Visual Studio 2005 installed windows PC and tried to compile. The first one was apparently failing because of the problem I mentioned before. However, the last one compiles and runs fine for both release and debug targets.
I used Boost Consulting's BoostPro 1.34.1 installer. My main.cpp file is below, you need to change the full_path_to_the_main.cpp.
HTH,
emre
int main()
{
boost::iostreams::grep_filter filter("main");
boost::iostreams::filtering_istream is;
is.unsetf(std::ios::skipws);
is.push(filter);
is.push(boost::iostreams::file_source("full_path_to_the_main.cpp"));
std::copy(std::istream_iterator<char>(is),
std::istream_iterator<char>(),
std::ostream_iterator<char>(std::cout));
}

Hi Paul,
I don't have a Visual C compiler around but the link error
you got is
probably not related with the grep filter.
For the run time bug, one of my friends had the same experience and we have found out that visual c cannot handle iterators of the empty strings. So I made a workaround for it, I don't know if it works, since I couldn't try it with VC yet.
Can you download, give it a try and let me know if it works for you?
Sadly, this gives me the same result in both debug (link failure - missing include?) and release (crashes).
:-(
Paul
