ThreadError when changing window size

[pocke]

Description

IRB displays ThreadError when changing the window size unexpectedly.

Reproduce

1. Start IRB with irb command
2. Change the terminal emulator size
   • It happens only when I make the window's width wider. No error when making it tight, or changing height.
3. It displays the following error
