[New-bugs-announce] [issue23541] Re module's match() fails to halt on a particular input

[Ceridwen]

New submission from Ceridwen:

Attached is a three-line script whose third line, a call to match() for a compiled regex, fails to halt on Python 2.7 and on 3.4 (after changing ur in front of the regex string to r to accommodate the change in Unicode handling).  I found it by stepping through the debugger so I suspect the problem is in the C backend, not the Python.
