--- Comment #1 from Martin Sebor <msebor at gcc dot gnu.org> ---
Confirmed with all supported versions of GCC as well as today's trunk of 7.0. 
A slightly simplified test case independent of libstdc++:

$ cat uu.cpp && /home/msebor/build/gcc-fortify-source/gcc/xgcc
-B/home/msebor/build/gcc-fortify-source/gcc -S uu.cpp
void oops () {
  auto fn = []{ };
  static_assert (!__is_literal_type (decltype (fn)), "oops");
}


uu.cpp: In function ‘void oops()’:
uu.cpp:3:3: error: static assertion failed: oops
   static_assert (!__is_literal_type (decltype (fn)), "oops");
   ^~~~~~~~~~~~~

I think this needs to be fixed in tandem with bug 70979 and so is probably
simplest to treat it as a duplicate.
