This does smell a bit like 'NOBTCFI = Yes' could "fix" this... If I understood correctly, we need to keep x11/qt5/qtwebkit for the time being, so someone with IBT hw should probably hunt this down. This might be a starting point: https://github.com/WebKit/Webkit/blob/main/Source/JavaScriptCore/llint/LowLevelInterpreter.asm More importantly, is there a qt6 equivalent of this code that people could keep hitting for a longer time?
