     Type:  Bugs                               |      Status:  new         
Milestone:  To Be Determined                   |   Component:  lexical_cast
  Version:  Boost 1.51.0                       |    Severity:  Problem     
 Keywords:  lexical_cast long trapv core dump  |  
-----------------------------------------------+----------------------------
 When compiling with g++ and option -ftrapv (trap overflow errors), a
 simple lexical_cast of a negative value causes a signal 6 dump:

 boost::lexical_cast<long>(std::string("-3333"));

 However, casting to double works fine.

 We're currently using gcc 4.7.1 on a OpenSuse 12.1 platform.
