I'm seeing a deadlock on a dual core Pentium D from libs/smart_ptr/test/sp_atomic_mt_test.cpp when USE_RWLOCK is defined (which causes it to use boost::shared_mutex). It works on uniprocessor.
How often, on what platform?
Every time, on a dual core Pentium D running XP64. The program is compiled as 32 bit with MSVC 7.1. It looks like a livelock rather than a deadlock, since the program keeps spinning its wheels at 100% but never completes. The writer thread is probably either blocked or starved. This happens on another (quad core) machine too for which I don't know the specs at the moment.
