        <pre>The following code triggers an assertion on Clang trunk:

------------------------------------------------------------------------------
template <typename T, T v>
struct integral_constant { };

auto false_ = integral_constant<bool, false>{};

template <typename T>
void f(T, decltype(false_));

int main() {
    f(1, integral_constant<bool, true>{});
}
------------------------------------------------------------------------------


The command line and output is

------------------------------------------------------------------------------
<span class="quote">> clang++-3.6 -std=c++14 -fsyntax-only test/worksheet.cpp</span >
