#8788: SIGSEGV on thread::join
------------------------------+----------------------
 Reporter:  anonymous         |      Owner:  anthonyw
     Type:  Bugs              |     Status:  new
Milestone:  To Be Determined  |  Component:  thread
  Version:  Boost 1.53.0      |   Severity:  Problem
 Keywords:  SIGSEGV, thread   |
------------------------------+----------------------
 Fedora 19, x86_64.

 The following program:
 {{{
 #include <boost/thread/thread.hpp>

 void myFunc()
 {
 }

 int main(int, char **)
 {
   boost::thread p(myFunc);

   p.join();
 }
 }}}

 When compiled with:
 {{{g++ -o bthread bthread.cxx -lboost_thread -D_GLIBCXX_DEBUG}}}

 Results in the following segfault (with -ggdb added):
