[Boost-users] Unordered map copy segfaults! (STL map does not)

Hi everyone,  

When I copy an unordered map, it segfaults. I am not having the same problem
with STL's map. Using an unordered map is essential for performance, so I
would really appreciate any help! Any ideas?

Here are the details:
================

typedef boost::unordered_map<unsigned long long, Dest> MyMap;

MyMap a; 
...
... // (I populate map 'a' here in a loop)
...
MyMap b;

b = a; // Segfaults! (also, I do not want to initialize b with a as in MyMap
b(a), I want to copy it later in the code.)

Where Dest is a struct:

struct Dest{
        bool			exists;
        int 			num;
        int 			src;
        int 			dest;
        unsigned short 	pos[64];
        
        Dest () {
                exists = false;
                num	= 0;
                src = 0;
                dest 	= 0;
        }
        
        ~Dest() {	}
};
