I get this when compiling the attached minimal test case. The condition for
getting an ICE seems to be that:
1. A template template parameter's type is defined with 2 or more parameters
2. The type (ignoring the first parameter) is defined in terms of previous
template parameters, and none of the type's parameters are typename
3. A default parameter instantiates the template parameter
This seems to go back to at least gcc 3.3.
To reproduce: g++ icetest.C
$ g++ -v
Using built-in specs.
Target: i686-pc-linux-gnu
Configured with: ./configure --with-gmp=/tmp/gcc-inst --prefix=/tmp/gcc-inst
--with-mpfr=/tmp/gcc-inst --enable-languages=c,c++
Thread model: posix
gcc version 4.3.0 20061201 (experimental)

Confirmed, not a regression, goes back to at least 2.95.3.
