6277	Checked iterators are not threadsafe	internet@…	viboes	"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
