[New-bugs-announce] [issue6156] Error compiling valid regex

[Daniel Eloff]

New submission from Daniel Eloff <dan.eloff at gmail.com>:

This works:

r'([xy])(?:\1)+'

This won't compile, "error: nothing to repeat"

r'([xy])(?:\s*\1)+'

I can execute this under other regex engines, and it seems to me that it
really should work.
