 Replying to [comment:1 RobK88]:
 > P.S. Same problem on Mtn Lion. The workaround is the same.  Build using
 a compiler with atomic support such as `clang-7.0`.
 >
 > But on Lion, for some reason, MacPorts also installed `clang-3.7` for
 the first time. I do not know whether this is related to the bug or just a
 coincidence.

 Work around seems to work on Mavericks...
