[Bug c++/28235] [4.0/4.1/4.2 Regression] ICE with static const member as default parameter in template

[reichelt at gcc dot gnu dot org]

------- Comment #7 from reichelt at gcc dot gnu dot org  2006-07-12 14:08 -------
Even shorter (valid) testcase:

=========================================
template<typename> struct A
{
    static const bool i = true;
    template<bool = i> struct B {};
    B<> b;
};
=========================================

This crashes since GCC 4.0.3 and was rejected by GCC 3.4.0 - 4.0.2.

------- Comment #12 from reichelt at gcc dot gnu dot org  2007-01-31 23:21 -------
This is now a rejects-valid again in GCC 4.0.4 (as in 3.4.0 - 4.0.2).
So this bug remains unfixed on the 4.0 branch, but is fixed in GCC 4.1.2.
