crashlog

WebKit crashes instantly on all 32 bit AMD processors and also on all 32 bit Intel processors (except Willamette or newer) since 2.19.90 (released on February 5, 2018).
This is because there is a hardcoded LFENCE instruction which can be only run by CPUs which have the SSE2 instruction set.
