When run Tools/demo/ss1.py under Linux and enter the formula "='0'*0x1000", the application will crash with the following message:

X Error of failed request:  BadAlloc (insufficient resources for operation)
  Major opcode of failed request:  53 (X_CreatePixmap)
  Serial number of failed request:  1025
  Current serial number in output stream:  1100

Any multiplier between 0x1000 and 0x1fff crashes. With multipliers >= 0x2000 only the number of zeros over 0x2000 is displayed. Multiplier between 0x3000 and 0x3fff crashes again.

Hint: The width of '0' in the used font is  8 pixels. 0x2000 * 8 = 2**16. If the width of cell is a 16-bit signed integer, it is negative for the number of zeros between 0x1000 and 0x1fff and wrapped after 0x2000 zeros.

It may be a bug either in Tkinter, in Tk, or in X Window.

I've done a small amount of testing on Windows (both with the issue18457 patch applied and without), and there is no such crash there.  Output isn't what is expected (the cell is lengthened, but nothing is shown), but no crash.
