$ clang++-tot valid.cpp -c
valid.cpp:13:15: error: use of class template 'A<int>::B' requires template

A< int >::B v(0, int_< 0 >());
^
valid.cpp:6:12: note: template is declared here
struct B{

1 error generated.
blaikie@blaikie-linux2:~/dev/scratch$ g++-tot valid.cpp -c
valid.cpp: In function ‘int main()’:
