This looks like a fallout from Doug's recent NestedNameSpecifier work.

$ cat t.cc
namespace std {
    template<typename T>     class vector     {
    };
}
template<typename T> static void foo(std::vector<T*> &V) {
    __PRETTY_FUNCTION__;
}
void bar(std::vector<int*> &Blocks) {
    foo(Blocks);
}

$ clang++ t.cc
clang: error: unable to execute command: Segmentation fault
clang: error: clang frontend command failed due to signal 1 (use -v to see
invocation)
