hi,
let's say i have something like this (very simplified):
<pre><code>
class base { void invoke() { this->foo(); } virtual void foo() = 0; };
class FirstDerived : public base
{
void foo()
{
// do stuff
}
};
class SecondDerived : public FirstDerived
{
// other not related stuff
}
int main() { SecondDerived *a = new SecondDerived(); a->invoke(); }
What i see in the debugger is that base::invoke() is called and tries to call this->foo(); (i expect FirstDerived::foo() to be called), the debugger takes me to some unfamiliar assembly code (probably because it jumped to unrelated areas) and after few lines i get segmentation fault.
am i doing something wrong here? :/
thanks in advance
