std::vector RTE(Run Time Error),

[ArbolOne]

class a_class{
public:
int id;
Glib::ustring fname;
};
std::vector<a_class>& my_class::my_method(){
a_class obj;
obj.id = 1;
obj.fname = "Me";

std::vector<a_class> v;
v.push_back(obj);

return v;
}
void a_method(){
std::vector<a_class> v;
my_class obj;
v = obj.my_method();
}

The program above gives me an class a_class{
public:
int id;
Glib::ustring fname;
};
std::vector<a_class>& my_class::my_method(){
a_class obj;
obj.id = 1;
obj.fname = "Me";

std::vector<a_class> v;
v.push_back(obj);

return v;
}
void a_method(){
std::vector<a_class> v;
my_class obj;
v = obj.my_method();
}

The program above gives me an RTE(Run Time Error), what am I doing wrong?what am I doing wrong?

What "Run Time Error"? Your code does not even compile.

If you want help, explain the context specific terms (such as ustring
and RTE) and post something that compiles!

class a_class{

std::vector<a_class>& my_class::my_method(){
a_class obj;
obj.id = 1;
obj.fname = "Me";

std::vector<a_class> v;
v.push_back(obj);

return v;
}

This return a reference to a temporary object which is a very bad idea.

void a_method(){
std::vector<a_class> v;
my_class obj;
v = obj.my_method();
}

The program above gives me an class a_class{
public:
int id;
Glib::ustring fname;
};
std::vector<a_class>& my_class::my_method(){
a_class obj;
obj.id = 1;
obj.fname = "Me";

std::vector<a_class> v;
v.push_back(obj);

return v;
}

So does this.

void a_method(){
std::vector<a_class> v;
my_class obj;
v = obj.my_method();
}

It should also give you compiler warnings for the two cases above.
