[issue9871] IDLE dies when using some regex

[Terry J. Reedy]

Terry J. Reedy <tjreedy at udel.edu> added the comment:

Verified as IDLE specific on WinXP, 3.1.2

With interpreter, I get
>>> import re; re.findall(b"\x.{2}", b"sdds\xd8")
ValueError: invalid \x escape

In an IDLE Shell window, the window immediately disappears when I hit return and the taskbar button disappears about a third of a second later.
