Preprocessed source to replicate the ICE
See the attached preprocessed source for replicating the ICE.
Here are the compiler specs:

Thread model: posix
gcc version 4.8.1 (Debian 4.8.1-10)
Note that I was also able to replicate the ICE with a GCC snapshot from Sept
17, 2013. On the contrary, GCC 4.7.3 is not affected.
