Crashes in applications using DirectFB-1.7.7 due to incomplete optimisation

Bug Description

My application crashes when trying to use X11 system on a gnome wayland desktop. Backtrace shows a Segfault in CoreGraphicsStateClient_Init().
This function was optimized shortly before release of 1.7.7 and they missed initializing a variable.

This is a known bug on other systems, see for example.

Attached patch is taken from openembedded project.
