The first thing I do before starting to tiller the belly, is to round all back edges. If you leave the edges square, all the bending stress is concentrated on the edge. Hickory / ipe should be bomb proof.  Without any pics, it's also possible your tiller was off, with a hinge at the fade where it broke.

It wasn't hinged, I was using a filleting gizmo and was down to thinning the tips. I hadn't rounded the edges yet, but this was my first attempt at a working back. You live, you learn, you break bows...

Yup... live and learn from mistakes! Been there. Next time, round off those corners before you start making it bend! I used to have a bucket in the corner of my shop called the 'barrel of shame.' Used to put the mess-ups there in plain sight as a reminder not to repeat past mistakes!
