breakpoint in eval.c

breakpoint in eval.c

[A Soare]

I put a breakpoint in Feval in eval.c on this line:

      args_left = original_args;
      numargs = Flength (args_left);

      CHECK_CONS_LIST ();                <=<= HERE is the breakpoint


In GDB I put the condition like this:

(gdb) info breakpoints 
Num Type           Disp Enb Address    What
9   breakpoint     keep y   0x08152b24 in Feval at eval.c:2266
	breakpoint already hit 23715 times
        silent
        if numargs > 30
          stop
        end
        continue

Now I called in editor






(+ 1 2 3 4 5 6 7 8 9 0
   1 2 3 4 5 6 7 8 9 0
   1 2 3 4 5 6 7 8 9 0
   1 2 3 4 5 6 7 8 9 0
   1 2 3 4 5 6 7 8 9 0)

C-x C-e.

However, the debugger did not stop in the breakpoint.

Can somebody explain me why please?

numargs is a Lisp_Object; to use it as an integer
you must divide it by 8.

or do:
         if numargs > 240
           stop
         end
