non-greedy can fail as you've seen, when using a large buffer.
>>> import pre, re
Traceback (most recent call last):
File "<stdin>", line 1, in ?
File "c:\python22\lib\sre.py", line 137, in search
return _compile(pattern, flags).search(string)
RuntimeError: maximum recursion limit exceeded
pre is the older engine and sre is the new one.
re.py has this:
engine = "sre"
# engine = "pre"
sre is faster in many cases.
There is a fix in the works for sre, but it won't be out for a while.
(I can't find the note about that)
