Do you have a copy of the style.css file referenced in the example?

server.zip There you have all the server files I was using I think

So far, I have not been able to make this crash on my Linux system. Running ./wrk -d 10000 -t 100 -c 100 http://localhost:8080 with no problem.

The 0xC0000005 error is often shown with running out of stack. Perhaps try it with adding -thread-stack-size 16777216 to force a 16MiB stack. Default on Windows is around 1MiB, I think.
