  There is no registered/known bug concerning URI parsingC in the 
current version 2.6.19. If you have a problem, please provide an example
showing up in the latest version, and it will certainly be fixed. If
the bug is confirmed and there is a patch associated usually the fix is
even faster.
  I'm a bit surprized that there would be a big error in the conformance
to 2396, this has been checked quite a lot, maybe it's in a not frequently
used part. In any case try to provide an example, see testURI.c in the 
distribution as a starting point.
