Hi guys, I’ve made a simple program to test the Process.create: require ‘rubygems’ require ‘win32/process’ pgname = “C:\Program Files\VideoLAN\VLC\vlc.exe” x = Process.create :app\_name =\> pgname.to\_s sleep 5 Process.kill(1,x) This works fine, but if a add at the begining require\_gem ‘activerecord’ I get a testBug.rb:8: [BUG] Segmentation fault ruby 1.8.4 (2006-04-14) [i386-mswin32] (i get the segfault at the “Process.kill” line…) any ideas ? I’m on a Windows XP Pro Edition , Service Pack 2 using ruby 1.8.4 Tks in advance, Ze Maria ---

As of 0.5.0 the Process.create method returns a ProcessInfo struct. So, your code should look like this: Process.kill(1, x.process\_id) That may not be the issue, though, since you say it works fine until you add the active\_record gem. Can you provide the full backtrace? Regards, Dan ---

Do a “gem clean win32-process” and try again. Also, make sure you don’t have it installed manually somewhere else. You can validate by printing out the Process::WIN32\_PROCESS\_VERSION constant. > btw I’m using ruby 1.8.4 should I upgrade to 1.8.5 ? If it still doesn’t work go ahead and try upgrading to 1.8.5.
