Comment 32 for bug 799202

The cause of (some part) of this bug is somewhere else. I removed all code from patch 503 and left only the part that adds new fields to structs. Effectively it looks like this:

+++ b/include/inputstr.h

     } last;

Simply applying this patch breaks pressure. Since this gets installed to /usr/include/xorg/inputstr.h, that means that someone (Qt probably) is using these structs incorrectly (creating them by themselves, building arrays or something else).
