It would've been nice if you'd mentioned that ;-)
Running a msvcrt.dll libpq with a msvcr80.dll pg_dump should work,
though; Windows programs are expected to cope with insane things like
mixing multiple C runtimes. It sounds like there's a bug where pg_dump
doesn't use the libpq memory management functions and instead does a
direct free(); changing those crash sites you found to use PQfreemem
should solve the problem. Try it and see.
Advise you how to do what?
By the way, you should be able to use a regular libpq compiled against
msvcr80.dll with your VC6 client app so long as the client app uses
PQfreemem to release memory allocated by libpq.
