working with tracepoints on an i686-pc-linux-gnu
>Description:
tstart fails when issued (unqualified).
>How-To-Repeat:
just execute tstart (or tfind none)
>Fix:
tracepoint.c:
   set_traceframe_context
 uses set_internalvar for trace_line twice.  Once it sets it as a pointer and once as an int.  Both should refer to an int?

Should be 


  if (trace_pc == -1)		/* cease debugging any trace buffers */
    {
      traceframe_fun = 0;
      traceframe_sal.pc = traceframe_sal.line = 0;
      traceframe_sal.symtab = NULL;
      set_internalvar (lookup_internalvar ("trace_func"),
		       value_from_pointer (charstar, (LONGEST) 0));
      set_internalvar (lookup_internalvar ("trace_file"),
		       value_from_pointer (charstar, (LONGEST) 0));
      set_internalvar (lookup_internalvar ("trace_line"),
		       value_from_longest (builtin_type_int, (LONGEST) - 1));
      return;
    }
