Code is wrong, because allocator must be defined as:

typedef std::pair<const int,double> MapValue_t;

instead of

typedef std::pair<const int,double> MapValue_t;

usual map declaration is:

template < class Key, class T, class Compare = less<Key>,
            class Allocator = allocator<pair<const Key,T> > > class map;

The sad part is that I think this bug should have been detected by the 
implementation, since it's quite common, and it's curious everything 
compiled fine with such type change.

I hope this helps,
