problem of stringstream

[李玉北 <leeight@xxxxxxxxx>]

hello

i'm using the code snippets

template <class T>
inline std::string to_string (const T& t)
{
    std::stringstream ss;
    ss << t;
    return ss.str();
}

but it cause a core dump sometime.
this is the backtrack information.

        ss = <incomplete type>

i using gdb debug my program, and x/d 0x41dd9ffc shows the value at
address 0x41dd9ffc is 2
i can't figure out what's the problem?

thanks a lot
