--- Comment #3 from Paolo Carlini <paolo.carlini at oracle dot com> 2012-01-03 22:46:33 UTC ---
If I consider Comment #1, and maybe I tweak it a bit like this:

bool testfun(void*)
{
  return true;
}

template<int i>
bool test()
{
  if (bool value = /* true */ testfun( []() { return 0; } ))
    return value;

  __builtin_abort();

  return false;
}

int main()
{
  test<0>();
}

I see what looks like a full fledged miscompilation: testfun always returns
true, thus test should simply return true!  Jason, what do you think?
