<pre>I am using my own build of clang (built using the scripts at
<a href="https://github.com/rsmmr/install-clang">https://github.com/rsmmr/install-clang</a>) and using a custom build gcc toolchain
using release version 4.8.3.
I use CMAKE to build my project, and just started experimented building it
using clang++ instead of g++.
Clang successfully builds all but one of my make targets. On the last one, it
fails with the following segmentation fault. I have attached the preprocessed
sources and run scripts below.
Let me know if you need any more information, or would like me to experiment
with some clang patches, etc.
Thanks,
Apurva
