Milestone:  To Be Determined        |   Component:  thread    
  Version:  Boost 1.40.0            |    Severity:  Regression
 Keywords:  valgrind,drd,threading  |  
------------------------------------+---------------------------------------
 OS: Ubuntu Jaunty, 64-bit

 Valgrind version: 3.4.1

 There are data races detected by valgrind tools drd and helgrind in
 boost::thread library examples. Problem appears in boost 1.37-1.40 at
 least and everything runs just fine in boost 1.34 (hard to test more
 versions, my work PC is not so fast and building takes a lot of time).

 Test cases:

 1) thread_group.cpp example from boost library

 2) attached file, my own minimal test case that provoked exploration
