Description Artem Pelenitsyn CLA 2011-09-10 11:49:13 EDT 
The problem is in perfectly valid C++ code as follows.

template<typename T> struct SS {};

template<
    template<typename T, typename S = SS<T> > class Cont> // "Type T could not be resolved." — on second occurence of T. Type: Semantic Error.
Cont<int>
f() {}

Sorry for silly question: where can I see the fix and when will it be possible to get it on my computer (through update or anyhow…)?
