Sorry, I know this in an old project.
When I try to run it in Visual Studio I get an exception in various places where std::equal was used if the strings are not the same length ( for example in the funcname_compare function when comparing "abs" to "+" ).
Exception: cannot seek string iterator after end
struct funcname_compare
{
bool operator() (const std::string &lhs, const std::string &rhs) const
{
if (equal(lhs.begin(), lhs.end(), rhs.begin())) // lhs is prefix of rhs
return false;
else if (equal(rhs.begin(), rhs.end(), lhs.begin())) // rhs is prefix of lhs
return true;
else
return lhs < rhs;
}
};
What is the expected behavior in the case when the strings are not the same length?
thanks!
