In the interest of closure, can you confirm (from the comment you made in another thread), that this now works for you after changing the stream open call to be:

std::ofstream strm("test.gz", std::ios_base::out | std::ios_base::binary);

I know that it works for me when I tried it.

Thanks for your interest in this, much appreciated. The problem persists, the written file can not be decompressed, I have worked my way around the problem, so it's not a issue for me anymore, but I would be happy to help track it down. I think it's very strange you can run without problems.

To clarify, when I built and ran it with VS 2008 and boost 1.35 it worked. When I just re-tried using VS 2008 and boost 1.45 or boost 1.46.1, it seems to produce invalid .gz files. Perhaps you can create a New Ticket and enter this as a bug at: https://svn.boost.org/trac/boost/newticket
