That's odd. Line 1100 is actually pure Ruby code:

binary_path = binary_path.unpack('Z*')[0]

I wonder if you've found a bug.

A few questions.

What version of Ruby are you running?
One click or hand built?
What version of win32-service?
Does it always segfault at the same place?

If it does segfault at the same place, can you open up your services explorer window and see what the next one on the list is?

Control Panel -> Administrative Tools -> Services

Or, if you could step through the debugger, I'd love to see what the 'binary_path' variable is set to when it dies.
