8447,Problems with 'repeat' in alternative parser,Nikita Rogatnev <nikita.rogatnev@…>,Joel de Guzman,"The behavior of the result parser unexpectedly depends from order of the 'repeat' statements within 'Alternative' parser.

As example:
""repeat(n)[...] | repeat(m)[...]"" works not like ""repeat(m)[...] | repeat(n)[...]"" in some circumstances.

I've been using the example from this [http://stackoverflow.com/questions/4009752/boost-spirit-bug-when-mixing-alternates-with-optionals] StackOverflow thread to identify problem (sample source is attached below).

The output of the result application:

in boost 1.44 (bug was fixed after stackoverflow thread):
  Success: '123FAA22'
  Failed to match.
  Success: '123F'
  Success: '1A22'

in boost 1.45 (seems to be correct):
  Success: '123FAA22'
  Success: '12AA'
  Success: '123F'
  Success: '1A22'

in boost 1.49 :
  Success: '123FAA22'
  Success: '12AA12AA' (Incorrect)
  Success: '123F'
  Success: '1A22'",Bugs,closed,To Be Determined,spirit,Boost 1.49.0,Regression,fixed,,
