A word of warning: the links on the demo page http://lcamtuf.coredump.cx/afl/demo/ lead to pages with images that can make your browser use up all your memory and your system will be unresponsive until the OOM killer kicks in. I admit that it's my fault for not reading the warning on the very page I'm linking, but I imagine there are others like me, so here.

WARNING: some of the demo pages will crash your browser.
