symbols::add destroys existing values

[olafvdspek@…]

This code echoes 0 instead of 1, which is not expected. Is this a bug?

#include <boost/spirit/include/classic_symbols.hpp> #include <iostream>

using namespace boost::spirit::classic; using namespace std;

int main() {

symbols<int> s; s.add("a", 1); s.add("a"); cout << *find(s, "a") << endl; return 0;

}

This is intended behaviour and not a bug.

In that case it should be documented.
