#7814: Signal 6 coredump on lexical_cast with gcc option trapv
-----------------------------------------------+----------------------------
 Reporter: Bernd Raum <braum@…> | Owner: apolukhin
     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.
