@DarkRoku : static_cast solves it indeed

Graphics / [SOLVED] weird crash in sf::thread

« on: October 03, 2016, 07:07:27 pm »

Hi,

While switching from SFML 2.3.2 to 2.4.0 on a big project, I run in a rather weird crash...

Here is a simple version :

class Base
{
public :
    virtual void foo(){};
};

class Deriv
    : public Base
{
public :
    virtual void foo(){
        printf( "hello\n" );
        sf::Font zFont;
        zFont.loadFromFile( "depend/calibri.ttf" ); //ok!
        sf::Text zText( "yolo", zFont );
        zText.getGlobalBounds();    //crash
    }
};

int main()
{
    Deriv instance;

    sf::Thread thread( &Deriv::foo, &instance );
    thread.launch();

}

1. In this example, the program crash as sool as getGlobalBounds is called.
(More precisely, it only works fine if we remove this call - my debugger is lost and cannot help more)

2. When creating the thread, if we give Base::foo instead of Deriv::foo (which should be the same), I get an error on the SFML code.

error: must use '.*' or '->*' to call pointer-to-member function ...

Note : everything was fine on SFML 2.3.2

I use Code::Blocks with mingw32-gcc-4.9.2

Have you a clue where it can come from ?
Can it be because of a bad library/compiler configuration ?
