Segmentation Fault in functions.rb:317

[fauziaabbasi]

I have a Windows Security box open and am trying to access it via rautomation. I can get the handle for the box, but when I run any rautomation feature, it gives me segmentation fault. Here is my script:

require 'watir' require 'rautomation'

ww = RAutomation::Window.new(:title=>"Windows Security") ww.exists?

here is the error: C:/Ruby193/lib/ruby/gems/1.9.1/gems/rautomation-0.7.2/lib/rautomation/adapter/win_32/functions.rb:317: [BUG] Segmentation fault ruby 1.9.3p194 (2012-04-20) [i386-mingw32]

Hi Jarmo,

We just saw this too and I think it might have been related to an FFI version. Let me know if you need help reproducing it and I can get the details for you.

This is caused by this (https://github.com/ffi/ffi/issues/213) and fixed in ffi version 1.1.3.
