Subject: QRasterPaintEngine::alphaPenBlt（）segment fault

Dear All:
I run a qt5 case on the platform directfb with HW acceleration . I find the function
void QRasterPaintEngine::alphaPenBlt(const void* src, int bpl, int depth, int rx,int ry,int w,int h)
runs a segment fault because of the surface buffer address is old .  How can I get the new address
here or how to call the  QDirectFbBlitter::doLock() here ?

Best Regards
Nancy
