5.3.2, 5.4.0
Description
We encounted a crash on some virtual machines with Qt 5.4.0 in convert_RGB_to_RGB16_inplace, because it is setting newData to 0x3c.
This crash is reproducable in all qtwebkit-examples/examples/webkitqml examples: just execute them, they're crashing without user interaction. Also, widget examples are not affected.
The attechments contain the stack traces of flickrview.exe and youtubeview.exe
I've also attached the output of sysinfo32
