The file which causes the internal error.

Compiling the attached file will cause an internal compiler error in gcc 4.7.0
under 32-bit Ubuntu 12.04:

g++-4.7 -std=c++11 rec_constexpr.cpp

...
constfft.cpp:16:47: internal compiler error: in cxx_eval_indirect_ref, at
cp/semantics.c:7400

If the copy constructor of Foo is removed, it is clang 3.2 (trunk 156580) which
will then fail.
