My money is on Norton AV as the problem.

I found some old notes in the archive:
http://sourceware.org/ml/crossgcc/2002-08/msg00050.html

It's a WAG for sure, but considering how most new AV software hooks
into every single running application and checks it for suspicious
actions, it's a good one.

If you can't tell Norton to ignore everything under your cygwon root,
you can try uninstalling it.
