Any Bug?

[david0002004]

Here is the code:

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

When I uses this function to convert an int to string, I got a core
dump. But I couldn't see anything wrong in the function. Thanks for
your help.

Are you sure this is your actual code? I could think it might core-dump
if you attempted to return a reference.

Or T is a UDT with something wrong in it's implementation of operator<<...

This code will not core dump, surely! It is never executed.
It will not even compile because of the missing includes.

Maybe. But this says nothing about the invisible rest of your code.

Most probably you passed a dangling reference to To_String.

Oops, missed that the op specified T as 'int'.
