Fix soundness bug described in #29859 #35745

jroesch · 2016-08-17T05:57:02Z

This is an attempt at fixing the problems described in #29859 based on an IRC conversation between @nikomatsakis and I today. I'm waiting on a full build to come back, otherwise both tests trigger the correct error.

Thanks @alexcrichton, not really sure why it wasn't building, been moving apartments this weekend so haven't had any time to chase it down.
