5523	Crash with singleton_pool in multithreaded mode	philippeb8@…	Chris Newbold	"Hi,

I am making calls to singleton_pool::ordered_malloc() with 2 different threads and the application is crashing.  The code can be found here:
https://svn.boost.org/svn/boost/sandbox/block_ptr/libs/smart_ptr/example/thread_test.cpp

And I get the following backtrace:
