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?

Hello sdcc-users,
I recently started using sdcc. I'm working on porting contiki-OS to an
8051 based system. I downloaded the latest source code (10-28-09)
compiled and installed, but when I compile contiki I get an assertion
failure in convilong.
The assertion message and compilation flags are:
sdcc -DCONTIKI_TARGET_WGN_BRIONE -DBRIONE_VER=4 -DBRIONE_DEV_VER=3

I'm attaching timetable.c and various header files as a zip, I don't
see any mult, div, or mod functions. I see only pointer dereferences (*).
Any advice you can give for a workaround would be greatly appreciated.
