#4484: bug in boost.thread on freebsd 8.0
------------------------------------+---------------------------------------
 Reporter:  shubin_evgeniy@…        |       Owner:  anthonyw  
     Type:  Bugs                    |      Status:  new       
Milestone:  Boost 1.44.0            |   Component:  thread    
  Version:  Boost 1.43.0            |    Severity:  Regression
 Keywords:  thread freebsd          |  
------------------------------------+---------------------------------------
 I use boost1.43 on FreeBSD 8.0-RELEASE-p3 amd64, installed from ports.
 Here is a simple program that causes an assertion:

   Assertion failed:
 (!pthread_cond_wait(&cond,m.mutex()->native_handle())), function wait,
 file ./boost/thread/pthread/condition_variable.hpp, line 20.

 during execution.


 {{{
 #include <boost/thread.hpp>
 #include <cstdlib>

 using namespace std;

 void ThreadFun(int number)
 {
     sleep(5);
 }

 int main(int argc, char** argv)
 {
     if (argc > 1)
     {
         pid_t pid = fork();
         if (pid < 0)
         {
             return EXIT_FAILURE;
         }
         else if (pid > 0)
         {
             return EXIT_SUCCESS;
         }
     }
     boost::thread th1(boost::bind(&ThreadFun, 1));
     th1.join();
     return EXIT_SUCCESS;
 }
 }}}


 Error occurs only when I execute program with command line arguments(when
 the process forks)
 and only on freebsd 8.0 (on ubuntu 10.04 x64 and on freebsd 7.3 amd 64 it
 works correct).
