Have you guys met this error before?

        I wrote a very simple function, as vector<double, 
__single_client_alloc> local(V.begin(), V.end());But under Gcc(g++ in fact), 
version 4.0.0, I got some error as "__single_client_alloca was not declared in 
this scope". I am wondering if some of you have met this before, you can help 
me out here, would you? Thank you!




1. The whole function is :
2 int main()
3 {
4       
5       using namespace std;
6       vector<double> V(100,5.0);              
7   vector<double, __single_client_alloc> local(V.begin(), V.end());            
8   return 0;
9       }



2. The gcc's version on my PC is :
$ gcc --version
gcc (GCC) 4.0.0 20050519 (Red Hat 4.0.0-8)
