CLONE -Tk crashes after invoking watir in a thread
--------------------------------------------------
Key: WTR-501
URL: http://jira.openqa.org/browse/WTR-501
Project: Watir
Issue Type: Bug
Components: Other
Affects Versions: 1.9.1
Environment: Windows 7, IE, PC
Reporter: Jason Fisher
Priority: Major
I use Tk to create GUI to invoke watir. When I click a button, IE
window should be opened. To avoid the freezing UI, I put it into a new
thread. This worked until everything finished and I closed Tk window.
There will be segmentation fault. I am not familar with Thread in
Ruby. Should I clean something after a thread is done?
Here is the simplified code. If you run this code, you will get a
segmentation erro when closing the Tk window.
require 'tk'
require 'watir'
root = TkRoot.new() { title "test watir" }
Thread.new{
browser = Watir::IE.new
sleep(2)
browser.close
}
Tk.mainloop()
Here is the error msg:
segerr.rb: [BUG] Segmentation fault
