Just a hunch: did you take those apr libs you're linking against from an Apache msi install? Or did you build them yourself with the same MSVC9 environment? I just remembered the following from the INSTALL file:
-----
        Note that if you are not using Visual Studio 6 (and you want to
        run and test the server modules) then you must rebuild Apache
        from source -- do not use the stock MSI since mixing C runtime
        libraries is not supported.
-----

Maybe you are experiencing a similar issue with "mixing C runtime libraries"?

Note: I'm very unexperienced in building on Windows, but was trying to make a build myself yesterday with VC Express 2008 (based on a Makefile posted by Daniel Shahaf: http://svn.haxx.se/users/archive-2009-07/0764.shtml). I didn't get through it yet (got stuck on building openssl), and gave up around 3am this morning. Will try again this weekend :).

Johan
