c – Boost快速池分配器是否存在函数指针问题？

#include <map>
#include <boost/pool/pool_alloc.hpp>

int main()
{
    typedef const std::string key;
    typedef double* (*value)(const int&);
    std::map<key,value,std::less<key>> map_with_standard_allocator; // works
    std::map<key,std::less<key>,boost::fast_pool_allocator<std::pair<const key,value> > > map_with_boost_allocator; // fails
}

最后一行无法在MS Visual Studio 2008下使用Boost 1.40和1.48进行编译.然而,它在g 4.5.3(Cygwin)下编译得很好.

错误是：
