Off the top of my head:
- - How are you running Ruby/Rails? Administrator (i.e. via 'Run as..', or
as the higher-privileged-but-not-quite-and-actual-admin admin account)?
- - Could you stack trace the segfault? Chances are, it is always at the
same location, code-wise, but Vista distributes memory in a
randomish-way to make buffer overflows more difficult.
- - Is Ruby installed into a directory where only an elevated account has
write access (i.e. %windir%\Programs, or something similar)?

I've had no issue with Ruby installed into %windir%\Ruby on Vista in
both RC2 and RTM pre-SP1.
