--- Comment #3 from Martin Sebor <msebor at gcc dot gnu.org> ---
The first revision that I have access to that shows the ICE is r125126 but I
suspect the root cause is actually r125062.  Prior to that, GCC rejected the
code with the error below:

t.C:8: error: parameter packs not expanded with `...':
t.C:8: note:         ‘T’
t.C: In function ‘int main()’:
t.C:14: error: no matching function for call to ‘B<int>::foo()’
