error: moving a temporary object prevents copy elision on make check

[semaj]

Following the build instructions in the readme. gclient sync worked fine, but make -C certificate-transparency check produces the following:

  CXX    cpp/proto/serializer_v2.o
cpp/proto/serializer_v2.cc:97:10: error: moving a temporary object prevents copy elision
      [-Werror,-Wpessimizing-move]
  return std::move(OID(oid));
         ^
cpp/proto/serializer_v2.cc:97:10: note: remove std::move call here
  return std::move(OID(oid));
         ^~~~~~~~~~        ~

I'm on Ubuntu 12.04 LTS.
Relevant versions:

$ clang++ --version
clang version 3.9.0-svn274430-1~exp1 (trunk)
Target: x86_64-unknown-linux-gnu
Thread model: posix
InstalledDir: /usr/bin

$ cmake -V
cmake version 3.2.3

Any ideas? Thanks!

Luckily for you, I think commit e11013b might have fixed that?

Could you give that a try and either close this or let us know if it didn't? Thanks!
