Comment (by samalone_at_[hidden]):

 I believe that I have encountered the same problem, and have a test case
 that consistently demonstrates the bug. I have attached the code as
 "Test.cpp". If you compile and run this program as-is, it will
 consistently fail with a bus-error, assertion failure, or infinite loop.

 If you compile the test program with -DEXTRA_MUTEX, the code wraps the
 managed_shared_memory calls with an extra scoped_lock<named_mutex>. This
 works around the bug, so it certainly seems that the internal mutex in the
 managed_shared_memory class is being ineffective.

 My computer is a PowerBook G4 running Mac OS X Leopard 10.5.3. The
 compiler is powerpc-apple-darwin9-gcc-4.0.1 (GCC) 4.0.1 (Apple Inc. build
 5465). I have not tried my test case on other platforms.
