I’m on Windows 2003, testing a possible upgrade from 1.8.6 to 1.9.1.

I receive a segmentation fault error when simply requiring Win32/Service  
(nothing else in the script), which faults in win32/api.so.

## Code:

## require ‘win32/service’

## Result:

This looks like a basic Ruby issue, not a Rails issue. As such, you’ll  
probably get better help on the main Ruby list.

## Best,

You’re using a precompiled binary that was compiled for 1.8.x not  
1.9.x. That’s why it’s failing. You’ll need to compile from source if  
you want to use it with 1.9.x.
