  * status:  new => closed
  * resolution:  => invalid

Comment:

 The observed behavior is in line with the one specified in the reference:

 <http://www.boost.org/libs/statechart/doc/reference.html#forward_event>

 Line number 38 of bug.cpp currently reads ...

 return forward_event();

 Replace this with ...

 return discard_event();

 ... and the program should then work as expected.

 Note that forward_event() should only be used in cases where a react
 member function determines that the passed event should be handled either
 in an outer state or a different orthogonal region.
