I'll bet it has nothing to do with cvp directly (someone else up the parent
tree is using those file handles already),  but has to do with the
equivalent of a "start /i".

What happens if you start a session with "start /i" and run your
compile from there?

And now you are _for sure_ overwriting some memory beyond
the crt's statically allocated _files[20] array.

I don't think it is possible to get around this problem by patching cl.exe.
