>Description:
The compiler is generating a nested template class using the wrong type. The attached program generates the following output:
1) void foo() [with _T = int]
2) c1<_T>::c1() [with _T = int]
3) c1<_T>::c1() [with _T = long int]

The second line should be the same as the 3rd line. I think the 'typename' keyword is problematic.
>How-To-Repeat:

>Fix:
Find a way not to use the 'typename' keyword.
