Summary: internal compiler error: in cp_tree_equal, at
cp/tree.c:2371

C++ source
Trying to compile the attached C++ file gives an internal compiler error with
GCC 4.6.3 on Ubuntu 12.04 i386. On a newer x86_64 system running Arch Linux,
GCC 4.9.0 compiles the same file without any problem, so it's possible that the
bug has already been fixed and needs to be backported to 4.6.x.
