--- Comment #2 from Florian Hahn <Florian.Hahn at arm.com> ---
I could not reproduce the segfault with a recent build of clang++ (clang
version 4.0.0 (https://github.com/llvm-mirror/clang.git
7f60b40f08d9c4f13f9b5a7cbbd98468d3345100)
(https://github.com/llvm-mirror/llvm.git
bd807b784e82c1f26339d45f9bf64847f42575e4).



With `clang++ -std=c++14 -c guard.cpp` clang++ produces the following errors:

guard.cpp:19:15: error: cannot initialize return object of type
'result_of_t<(lambda at
      guard.cpp:49:37) ()>' with an rvalue of type 'result_of_t<(lambda at
guard.cpp:50:16)
      ()>'
  else return guard(rest...);
              ^~~~~~~~~~~~~~
guard.cpp:49:24: note: in instantiation of function template specialization
'guard<(lambda at
      guard.cpp:49:37), bool, (lambda at guard.cpp:50:16)>' requested here
  auto type_mismatch = guard(false, []() { return 5; },
                       ^
1 error generated.


------

Erik's example also produces a proper error message.

I'll close this issue for now.
