Where? The term "crash" rarely means anything useful.

Have you tried:
class A
{
public:
A() {}
A(const string& s) {}string f() { return "hello world"; }};
class B : public A
{
private:
string s;
public:
B()
{
s = f();
}
};

In class A, does it still crash if you make the f() method static? You are using A's method before A is ctor'ed. It looks like it shouldn't matter, but who knows, maybe some static consts are not available until after the first inst of the class is created? Sounds doubtful, doesn't it.

Thanks NealAB, Yeah I got your point! I think that is only happening. I was trying to use A's method before it was created. Thanks again...
