Why does Cppcheck not find this obvious array out-of-bounds error?

I installed the Cppcheck tool for static code analysis of my C++ project and got the feeling that it performs poorly. For example, can anyone tell me why Cppcheck is unable to find an array out-of-bounds error in the following code?

void f(int c) { 
    char *p = new char[10]; 
    p[c] = 42; 
} 

void g() { 
    f(100); 
} 

There's an online demo where this code can be conveniently checked using Cppcheck. All it comes up with is a memory leak at line 4, no signs of a potential buffer overflow.
