Crashes if Scrollback lines set to 0 and window is resized to smaller than buffer contents

[GoogleCodeExporter]

What steps will reproduce the problem?
1. Set "Scrollback lines" in Options->Window to 0 and apply settings
2. Reset terminal (Alt-F8)
3. Produce some output (e.g. "head /dev/random" or "echo 123")
4. Resize window to smaller than what has been output (e.g. to 1 row)
5. Observe program exit

What is the expected output? What do you see instead?
   Expected would be for mintty to resize, pushing contents which don't fit out of the buffer. Instead, the program crashes.

What versions of mintty, Cygwin/MSYS, and Windows are you using?
   mintty 0.9.6
   Cygwin 1.7.9-1
   Windows XP, SP3

Please provide any additional information below.
   All settings besides Scrollback lines = 0 left at default.
