This is with today's g++ 4.3, but has been there for a few weeks:
Configured with: /proj/geometrica/home/GCC/trunk/configure
--with-gmp=/proj/geometrica/home/MPFR/MPFR-2.2.1/FC5 --disable-shared
--disable-nls --enable-languages=c++,fortran
--prefix=/proj/geometrica/home/GCC/Linux-fc5-4.3
Thread model: posix
gcc version 4.3.0 20070819 (experimental)
Compiling the attached preprocessed file with "-c -O2" produces the
following ICE. Note that it is not deterministic: you usually need
to repeat the compile 10-20 times to see it...

internal compiler error: canonical types differ for identical types const

Please submit a full bug report,
with preprocessed source if appropriate.
See <URL:http://gcc.gnu.org/bugs.html> for instructions.
I have also been able to reproduce it with only "-O".
