Issue #15159 has been updated by jeremyevans0 (Jeremy Evans).

Status changed from Open to Third Party's Issue

The segfault is in a external gem (rautomation) that uses FFI: https://github.com/jarmo/RAutomation/blob/7314a7e6f8bbba797d276ca1950abde0cba6897a/lib/rautomation/adapter/win_32/functions.rb#L18-L19

It looks very similar to a bug report on their bug tracker: https://github.com/jarmo/RAutomation/issues/122

Please work with the rautomation developers to resolve this issue.

Hello,

The following options are not working for the win32screenshot gem (or possibly rautomation) in Ruby 2.5.1.  The error I get is below.  I have attached a log as well.  The code works in Ruby 2.4.4.

C:/Selenium_Ruby/runtime/lib/ruby/gems/2.5.0/gems/rautomation-0.17.0/lib/rautomation/adapter/win_32/functions.rb:298: [BUG] Segmentation fault


Sample code...

filename_and_path="c:\\myscreenshot.png"

puts "Attepting to take screenshot of foreground using Win32screenshot gem...\n\n"
Win32::Screenshot::Take.of(:foreground).write(filename_and_path)

puts "Attepting to take screenshot of window with title #{window_title} using Win32screenshot gem...\n\n"
Win32::Screenshot::Take.of(:window, :title => /#{window_title}/i).write(filename_and_path)	#Another option

puts "Attepting to take screenshot of desktop using Win32screenshot gem...\n\n"
Win32::Screenshot::Take.of(:desktop).write(filename_and_path)
