This code doesn't compile for me at all:

r3.cc: In function ‘int main(int, char**)’:
r3.cc:8:27: error: expected primary-expression before ‘(’ token
  auto thread = std::thread([&, =val]() { func(val); });
                           ^
r3.cc:8:32: error: expected identifier before ‘=’ token
  auto thread = std::thread([&, =val]() { func(val); });
                                ^

clang++ rejects it, too.
