Athlon XP doesn't have SSE2 instructions, so it crashes with exception (Invalid opcode exception) as in the report, so this is expected. The question is can it be detected at run-time and a warning displayed instead of a crash though?

Unfortunately this is now hardcoded in the javascript code and there is no way to disable it. The lfence instruction is used there to mitigate spectre and meltdown attacks. So, I'm just making Web+ abort in that case. You can run NetSurf or other browsers, but WebPositive is now officially out on such architectures. Sorry about that.
