Abe-san, Please make sure you use the same message size in your application and your test case. Using small messages can hide some application level deadlock.

My Environment : OSX 10.9.5, Apple LLVM 6.0 >(LLVM 3.5svn), OpenMPI 1.10.0 The thread is wxThread from wxWidgets Library >(3.0.2) which is a wrapper of pthread.
