It seems it never goes into if (!child->pid) {...} part below:
Can you add debug_printf_exec() as shown wit '+' and test again?

                if (child->argv)
                        debug_printf_exec(": pipe member '%s' '%s'...\n", child->argv[0], child->argv[1]);
                else
                        debug_printf_exec(": pipe member with no argv\n");

                /* pipes are inserted between pairs of commands */
                if ((i + 1) < pi->num_progs) {
                        pipe(pipefds);
                        nextout = pipefds[1];
                } else {
                        nextout = 1;
                        pipefds[0] = -1;
                }

                /* XXX test for failed fork()? */
#if BB_MMU
                child->pid = fork();
+               debug_printf_exec(": vfork returned %d\n", child->pid);
#else
                child->pid = vfork();
+               debug_printf_exec(": fork returned %d\n", child->pid);
#endif
                if (!child->pid) { /* child */
