Description Stephan Bergmann 2004-06-04 15:00:43 UTC 
The code

  namespace a {}
  namespace b {
    namespace c = a;
    namespace c = a;
  }

fails for 3.4.0 ("declaration of 'namespace c = a;' conflicts with previous
declaration 'namespace c = a;'"), but works for 3.3.3.  The simpler code

  namespace a {}
  namespace c = a;
  namespace c = a;

works for both 3.4.0 and 3.3.3.
Comment 1 Andrew Pinski 2004-06-04 15:09:12 UTC 
Confirmed, this is a regression, I do not know if this works in 3.4.1 but it does work in 3.5.0.
Comment 2 Wolfgang Bangerth 2004-06-04 15:44:02 UTC 
Mark fixed this for 3.4.1 and mainline a few days ago.
