Try turning up logging also to DEBUG in native.logger.

Hmm, actually what it might be doing is failing "gracefully" to initialize
and that's somehow causing the crash. I'd have to see if I can simulate
that. That would point to a problem creating files or what have you and it
returning out of the startup routine with a failure.

I don't know how to get a trace on anything recent, I don't use Windows
much anymore. Getting the debug files used is mostly a lot of path
changes. You'd change the system path to add debug on the end of the lib
directory, and then the path to the filter and extension inside IIS. I
would ignore the Service control definition for shibd and let it fail, and
just run shibd from the command line out of sbin/debug/shibd -console

But I'd focus on the logging first. The chances of it not being
permissions are extremely low. So at the end of that day, that's what
you're going to have to find.
