The above assert indicates that --db-attach is not implemented on darwin.
You could however try the Valgrind gdbserver, which is supposed to work (at least, I manually tested it on Darwin something like one year ago on a 3.7.0 SVN). You could try to investigate why abort is called by using 2 GDBs to debug: * a native run * a run under Valgrind and see at which point/instruction their executions are diverging. (e.g. put breakpoint in _SCSessionUniverseByUIDAcquireAndLock and then use stepi or similar.).
