Yes , that's the question.However I've discovered by chance that the gdb
steps correctly into the methods the fifth time:

(gdb)s
 obj_msg_lookup error (receiver =  0x....... op = 0x........ )
                at  /src/Swarm/swarm/libobjc/sendmsg.c  : 143
 143                /src/Swarm/swarm/libobjc/sendmsg.c : No such file or
directory.
