#6248: multi_pass_iterator not flushed automatically by expectation operator

     Type:  Bugs                                   |      Status:  new    
Milestone:  To Be Determined                       |   Component:  spirit 
  Version:  Boost 1.47.0                           |    Severity:  Problem
 Keywords:  multi_pass_iterator, flush_multi_pass  |  
---------------------------------------------------+------------------------
 Parsing a 2GB file, multi_pass_iterator throws std::bad_alloc when it
 tries to push_back the ~1.2GB'th item, even though expectation operator is
 used with a record based file whose max record length is ~200 chars.
 For example:

   start %= header > *rec;

 I also tried:

   start %= header > flush_multi_pass *rec;

 which resulted in no effect.

 note: 1.47.0 required modifying flush_multi_pass.hpp to be the same as
 1.48.0 impl to avoid compilation errors
