Well, first it looked like that whe have a very similar problem with our code than in the shared_ptr_test (did not dig deeper into both yet):
Program received signal SIGSEGV, Segmentation fault si_code: 1 - SEGV_MAPERR - Address not mapped to object. 0x5c17e30 in <unknown_procedure> () (gdb)
But now, as the shared_ptr_test works with -O2 (at least for me), I just tried our code with -O2, and it still does not work. So it also could be another (gcc?)problem than for the shared_ptr_test.
Does it still not work with BOOST_SP_DISABLE_THREADS or BOOST_SP_USE_PTHREADS defined? If so, it's a general problem, not caused by the platform-specific atomics; it could be a compiler backend bug, and should probably be reported to the GCC Bugzilla. Can you try a 4.x g++? It might have even been fixed. The Boost test pages are at http://engineering.meta-comm.com/boost-regression/CVS-RC_1_34_0/developer/ linked from the main page, top right corner.
