works for me on the 4.7 branch (x86_64-linux) with preprocessed source from
using 4.7.2.

So it might be triggered by a libstdc++ change?

Can you attach preprocessed source?

Also fails with GCC 4.7.0  GCC 4.6 ICEs for me with

in dependent_type_p, at cp/pt.c:18136
Please submit a full bug report,

See <http://gcc.gnu.org/bugs.html> for instructions.

(confused by earlier errors)

4.5 seems to "work".

Factoring in libstdc++ changes the point of the regression.
