Hi,
I'm not really sure I can help with pages to help you out with pages
explaining howto debug Windows apps, though I'd be content with the
informatiion you have below -- it's a pretty good start!
As for your output I imagine it crashes on the line it does because that's the
first time it tries to access the memory pointer you pass through in the line;

If it were me, I'd want to know what 'index' was... If it was accessing
something outside the bounds of your array, for instance. I am not sure what
you're having trouble interpreting, exactly. You know the last function
called from what's on the stack, you know the line calling that [act()] and
you even get an idea of the precise line it crashes on. I wish Windows were
this kind to me half the time; I seem to spend my time hunting through map
files.
Adding some OutputDebugString()s with the necessary definitions, or your own
form of debug logging, should sort that out for you.
One thing /I/ would like to know is; can I set up MSVC (6.0) to do the
equivalent of a core dump, and how can I load that into the compiler, like I
would do with gdb? I was thinking about shifting across to Windows (for
coding/testing only, the MUD will still run on BSD) but I find the core dumps
invaluable.
