#9466: shared_ptr fails with EINVAL on AIX 7.1 when compiled with atomic

     Type:  Bugs              |     Status:  new
Milestone:  To Be Determined  |  Component:  smart_ptr
  Version:  Boost 1.55.0      |   Severity:  Problem
 Keywords:                    |
------------------------------+-----------------------
 Boost shared_ptr sometimes fails with EINVAL (22) when compiled with gcc
 4.6.3 (65bits) on AIX 7.1.  It appears that this failure only occurs when
 atomic is activated as part of building the boost library (1.55).

 I noticed on AIX the library "libboost_atomic" was req'd, while that was
 not needed on other platforms such as rhel and ubuntu.

 To solve the issue on AIX I specified -DBOOST_THREAD_DONT_USE_ATOMIC while
 building the boost libs.

 Inside details:

 Line 73 at boost/boost/smart_ptr/detail/lwm_pthreads.hpp
 BOOST_VERIFY( pthread_mutex_lock( &m_ ) == 0 );
