--- Comment #1 from Sanjay Patel <spatel+llvm@rotateright.com> ---
The good news is that I think this is a duplicate of bug 18861. That bug was
fixed by:
http://llvm.org/viewvc/llvm-project?rev=209796&view=rev
Zhendong - if you could please update to TOT and confirm there's no more crash,
that would be great.
The weird news is that neither this test case nor the ones in bug 18861 caused
my CMake-built clang to crash prior to r209796. Only the autotools-built
(configure; make) clang crashed.
I tested on both Ubuntu 14.04 (clang TOT built by gcc 4.9) and OSX 10.9 (clang
TOT built by clang ~3.4).
Does anyone have any theories on how this could happen?
