Re: [Sdcc-user] sdcc: SDCCopt.c:707 convilong: Assertion `0' failed.

[Anthony A. <ant...@gm...>]

I located the source of the problem in timetable.h.

*  int i;*
   int t1, t2;

   t1 = t2 = t->size;
   for(i = *t->ptr - 1; i >= 0; --i) {
*    if(t->timestamps[i].id == id1) {*
       t1 = i;
       break;
     }
   }

I see that the array dereference would use multiplication with the int 
i.  I don't understand why this cause an assertion failure.

Any thoughts?
