[Bug c++/13289] New: internal compiler error : regenerate_decl_from_template, at cp/pt.c:10131

["gianni at mariani dot ws" <gcc-bugzilla at gcc dot gnu dot org>]

I can understand why this code has problems - it is recursive, I need to find a
way to make it not be so !  But the compiler spits out an "internal compiler
error" that probably needs a look at.

template <typename T, T N>
struct bit_count_templ
{
        static const T bit_count;
};

template <typename T, T N>
const T bit_count_templ<T,N>::bit_count = 1 + ( N == 0 ? 0 : bit_count_templ<T,
N & ( N -1 ) >::bit_count );


#include <iostream>

int main()
{
        std::cout << bit_count_templ<long,0x256500LL>::bit_count;
}
