--- Comment #1 from Truls Johnsen <trulsjo at gmail dot com> ---
Reduced the test case to only include <initializer_list> and changed max to a
one-liner that still shows the same behavior. Removing constexpr from max, or
the (unused) template from a() makes the code compile:

#include <initializer_list>

constexpr
int
max(std::initializer_list<int> __l)
{ return *__l.begin(); }

template <class Src>
void
a() {
  const int v =  max({1});
}


I forgot to mention the host in the initial report:
Intel(R) Core(TM) i5-2300 CPU @ 2.80GHz
