Martin Sebor <msebor at gcc dot gnu.org> changed: What |Removed |Added ---------------------------------------------------------------------------- Status|UNCONFIRMED |RESOLVED Last reconfirmed| |2016-5-16 CC| |msebor at gcc dot gnu.org Resolution|--- |DUPLICATE Known to fail| |4.9.3, 5.3.0, 6.1.0, 7.0 --- 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. *** This bug has been marked as a duplicate of bug 70979 ***
