Confirmed.  We're back to an ICE.

I can also confirm that

http://gcc.gnu.org/ml/gcc-patches/2008-02/msg00212.html

does _not_ fix the problem.  We still ICE with

/space/rguenther/src/svn/trunk/gcc/testsuite/g++.dg/ext/vector13.C:6: internal
compiler error: canonical types differ for identical types const int __vector__
[] and const int __vector__ []^M
Please submit a full bug report,^M
with preprocessed source if appropriate.^M
See <http://gcc.gnu.org/bugs.html> for instructions.^M

FAIL: g++.dg/ext/vector13.C (internal compiler error)
FAIL: g++.dg/ext/vector13.C (test for excess errors)

Indeed.  I developed my 35049 patch in an old check-out (to avoid conflicts
with Doug's patch), but after updating the tree it fails for me too.

This is definitely a canonical-types bug.

       * tree.c (cp_build_qualified_type_real): When building a
       cv-qualified array type, build it as a unique type with
       build_cplus_array_type_1 and then adopt the unqualified type's
       main variant.
