     Type:  Bugs                     |      Status:  new            
Milestone:  To Be Determined         |   Component:  circular_buffer
  Version:  Boost 1.46.1             |    Severity:  Showstopper    
 Keywords:                           |  
-------------------------------------+--------------------------------------
 I encountered a problem whereby I was using the copy constructor of
 boost::circular_buffer in multiple threads.  The attached code
 demonstrates the problem.  The problem appears to be caused by the checked
 iterators, so does not occur in release builds.

 Actual behaviour: Segmentation fault.

 Expected behaviour: Program should loop indefinitely.

 Workaround:
 #define BOOST_CB_DISABLE_DEBUG

 Compilers tested:
 g++ 4.6.1
 Visual C++ 2010 (cl.exe 16.00)

 Platforms tested:
 x86_64-linux-gnu (Ubuntu 11.04)
 Windows 7 x64

 Boost versions tested:
 Linux 1.46.1.1 (Ubuntu)
 Linux 1.48.0
 Windows 1.46.1
