Category: Regular Expressions Group: None Status: Open Resolution: None Priority: 5 Submitted By: Markus F.X.J. Oberhumer (mfx) Assigned to: Fredrik Lundh (effbot) Summary: sre bug with nested groups

Initial Comment: sre incorrectly assigns non-matched inner groups.

See m.group(2) in the example below.

This bug seems to be present in all sre versions (tested with python 1.6.x, 2.0.x, 2.1.x and 2.2a4).

Markus

P.S. this seems not related to SF bug #468169
