Example1:(With Internal Compiler Error)

#include <iostream>
#include <string>
#include <boost\dynamic_bitset.hpp>

using std::cout;
using std::endl;

boost::dynamic_bitset<char> g_bs;//!!!!!!!!!!!!!!!!!!!!!!!!Here
void SetBitSet(const std::string & str)
{
 boost::dynamic_bitset<char> bs(str); 
// g_bs = bs;
}

int main()
{
 return 0;
}

Example 2:(Without Internal Compiler Error)

#include <iostream>

using std::cout;
using std::endl;

//boost::dynamic_bitset<char> g_bs;//!!!!!!!!!!!!!!!!Here

void SetBitSet(const std::string & str)
{
 boost::dynamic_bitset<char> bs(str); 
// g_bs = bs;
}

int main()
{
     return 0;
