I have just documented a nice case of this on my blog at the Intel Developer Zone (IDZ), where the Simics team found a bug in how Xen deals with MPX instructions when using VT-x. Thanks to running on Simics, where scenarios not available in current hardware are easy to set up.

Since I happen to like virtual things, even the so-much-talked-about-it-hurts IT/server/desktop virtualization world this was a must-listen.
