--- Comment #1 from Tim Northover <t.p.northover at gmail.com> ---
It's another ARMFrameLowering.cpp bug. There is an earlier store that LLVM
thinks is going to the same slot, but it's miscalculating the offset from r6 in
the load because it thinks the neighbouring "sub sp, sp, ..." affects it.

Should be fixed in r348591.
