   I'm getting this assertion failure on ia64-linux when stepping after a
   breakpoint with a signal also being delivered.  Both calls to
   insert_step_resume_breakpoint_at_sal are coming from the two calls to
   insert_step_resume_breakpoint_at_frame in handle_inferior_event.  In both
   calls the actual address where the breakpoint is to be set is the same.  I
   haven't been able to come up with a small test case, this happens while
   debugging Emacs.

I'm seeing the same problem on NetBSD/amd64 in the regular testsuite
(sigstep.exp).  Haven't found the time yet to look into it though.
