I'm working on a program with which we are using the boost::program_options module and ran into an odd assertion in the xstring library used by said module. The program was compiled using VC++ 8 and the Platform SDK Windows Server 2003 SP1. The assertion occured when the total string length (spaces + options + arg defaults + description) was over about 80 characters and was not formatted with a \n or the like. The assertion was xstring:173 ("_Myptr + _Off <=(((_Mystring *)this->_Mycont)->_Myptr()+((_Mystring *)->_Mycont)->_Mysize)&&+_Off >= ((_Mystring *)this->_Mycont)->_Myptr()", 0). and a call stack on one of the programs this occurred on can be seen below. This has occurred for a number of applications we have that all have the same condition. Thank you in advance for your assitance
