Here is a current snapshot of the bug.

Project: Python
Category: Library
Status: Open
Resolution: None
Bug Group: None
Priority: 7
Summary: sre/pre bug

Details: Compiling the simple pattern '(' with pre raises an exception while sre compiles it sucessfully. Further, the regex object that sre.compile returns will match any string.

Using Python 1.6b1 (#0, Aug  7 2000, 12:30:24) [MSC 32 bit (Intel)] on win32,

  >>> import sre
  >>> regex_ = sre.compile('(')
  >>> regex_.pattern
  '('
  >>> regex_.search('abc').group(0)
  ''

while

  >>> import pre
  >>> regex_ = pre.compile('(')
  Traceback (most recent call last):
    File "<stdin>", line 1, in ?
    File "C:\Python16\lib\pre.py", line 243, in compile
      code=pcre_compile(pattern, flags, groupindex)
  pcre.error: ('missing )', 1)
