I got 'em all (below) and the problem is that 't' here == NULL:

383     suspend (void)
384     {
385       scm_i_thread *t = SCM_I_CURRENT_THREAD;
386     
387       /* record top of stack for the GC */
388       t->top = SCM_STACK_PTR (&t);
389       /* save registers. */
390       SCM_FLUSH_REGISTER_WINDOWS;


Program received signal SIGSEGV, Segmentation fault.
