[cfe-dev] Problems with Clang since upgrading compiler to Visual Studio 2015

That may be so but I'm not sure where the bug could be occurring because my
code is very simple; I literally just invoke the compiler. I've pastebinned
my code here: http://pastebin.com/wpS6VX5N

A weird thing is that when this invocation code is built into a debug dll
with optimization disabled (as I need in my project), I hit the previously
mentioned assert when running, but it works perfectly when it's compiled
straight into a debug executable. If I set the optimization level to O2
instead of disabled on the dll then it also works fine.
