Code causing segault with large -ftemplate-depth

Attached code compiled with clang++ -Wall -std=c++11 -c -ftemplate-depth=65536
causes clang 3.2 to segfault.

The attached code is obviously a little demanding on the compiler and segfault
only occurs with large -ftemplate-depth, but still a segfault is not nice and
might be triggered by more mundane code?

Note: gcc 4.8 has the same behavior, icc doesn't segfault :\
