That's what I did. This time I've attached the output log file.
Hopefully that might have some clues in it.

I just ran the exe through gdb, here is the output. It doesn't tell me
much but I have very little experience with gdb. Can anyone else see
what the issue might be?

Hi Rory,

I saw some things in your log about syswow64 dll's.  I don't know what
that is, but made me wonder if you're somehow linking with some 32bit
dll's and some 64bit ones?

Hmm. That's a thought. I'm very new to windows 7 and 64 bit
architecture. I assume all the system dlls are 64bit, so could it be
that some of my libraries, e.g., libsndfile are built as 32bit when I
should be using 64bit. As far as I know it's possible to grab a
pre-compiled 64bit version of libsndfile. I might start there and see
if it helps. Thanks.

Rory.

Thanks Steven. Updating my libsndfile got me over that hurdle. I'm
sure it probably says something about this in Mike's build
instructions but I haven't got around to reading them yet!
