Description Marcin Kwiatkowski 2006-12-02 11:50:50 PST 
In QPixmap::isNull()

"return (imageRenderer == NULL) || (imageRenderer->IsNull());"

C++ standard doesn't guarantee that (imageRenderer == NULL) will be evaluated before (imageRenderer->IsNull()) so compiler optimalisation can produce broken code.
Comment 1 Bradley Morrison 2006-12-03 08:23:54 PST 
True, this needs to be evaluated wrt our compilers.

Thanks for the feedback Marcin!
