<pre>Repro:
llvm-build\bin\clang-cl main.cc outline.cc -m32 /Fefoo.exe /O1 /Ob2 /GF /Oy-
/Oi /Os
foo
The executable crashes. Works fine without r256730, works fine in CL.
(Might be a code error, but the code is pretty short by now, and I still don't
see an error -- seems like some stack alignment thing)
Attaching main.cc and outline.cc momentarily. Not quite minimal, but fairly
small. outline.cc only exists to outline a single function, so that clang can't
optimize the program away.</pre>
