#12049: Assertion failure from detached threads during shutdown

Milestone:  To Be Determined            |  Component:  thread
  Version:  Boost 1.60.0                |   Severity:  Regression
 Keywords:                              |
----------------------------------------+------------------------
 I'm observing assertion failures coming from detached threads during
 shutdown (i.e., the main thread is in static destruction):
 {{{
 libs/thread/src/pthread/thread.cpp:149: void
 boost::detail::set_current_thread_data(boost::detail::thread_data_base*):
 Assertion `!pthread_setspecific(current_thread_tls_key,new_data)' failed.
 }}}
 I'm seeing this on both Linux and Mac platforms; and the problem appears
 to have been introduced in the 1.60.0 release; 1.59.0 did not exhibit the
 problem.

 Stacks from these threads at the time of the assertion failure look like
 this:
 {{{
 #0      0x00007fff95104002 in __pthread_kill ()
 #1      0x000000010356944e in pthread_kill ()
 #2      0x00007fff9ef566e7 in abort ()
 #3      0x00007fff9ef1ddc7 in __assert_rtn ()
 #4      0x0000000100a4ff90 in
 boost::detail::set_current_thread_data(boost::detail::thread_data_base*)
 at
 /Users/mcdanb/Build/buildpackages/API/pkg_build/boost_1_60_0/libs/thread/src/pthread/thread.cpp:149
 #5      0x0000000100a50141 in boost::(anonymous
 namespace)::thread_proxy(void*) at
 /Users/mcdanb/Build/buildpackages/API/pkg_build/boost_1_60_0/libs/thread/src/pthread/thread.cpp:185
 #6      0x00000001035679f9 in _pthread_body ()
 #7      0x0000000103567976 in _pthread_start ()
 #8      0x0000000103564fbd in thread_start ()
 }}}
 So, the thread appears to have completed any work it was doing. The
 problem is not reproducible 100% of the time; but when it happens (which
 is not infrequent), I appear to see one assertion for each detached thread
 that is still present during static destruction.
