ASSERTION FAILED: !hasDataLabel()
../../../Source/JavaScriptCore/yarr/YarrJIT.cpp(653) : void JSC::Yarr::YarrGenerator::BacktrackDestination::setDataLabel(JSC::AbstractMacroAssembler<JSC::X86Assembler>::DataLabelPtr)

Reproduced from r91843 with QtTestBrowser on linux in debug. Just had to log in to facebook, I could see my home page flash and the assert would pop.
