gcc 4 (about RC1) miscompiles khtml, in fact something in CSS, which basically leads to all websites being misrendered. I can't easily reduce the testcase, but have applied the whole preprocessed source of css/cssstyleselector.ii. It is to be compiled with g++ -O2 -fPIC -march=i586 -mtune=i686 -fno-exceptions. A more detailed analysis will follow, as we've found out some things already.
