I've been trying to track down the origin of this bug and so far I'm out of luck. I tried first switching to "luaotfload" style font loading with 

   \font\1={xyz}

instead of XeTeX-style

   \font\1="xyz"

but that produced even more problems.

This *could* be a bug in the LaTeX2e kernel, but I don't have time to wade into the NFSS at this stage.

I've added an issue for this bug:

    http://github.com/wspr/fontspec/issues/issue/74

To be addressed when possible.
