Wow. What embedded system is it that doesn't support a call stack that is *only* 35 levels deep?
The 12-bit PIC microcontrollers are limited to 2-level stacks, and many of the smaller 14-bit PICs are limited to 8-level stacks.
Not that I expect that Andrew is trying to get SQLite running on a small PIC. Such a processor likely doesn't even have enough code space to run SQLite in the first place.
There is a serious point to this, which is that embedded processors can go to serious extremes in the name of efficiency or cost. It wouldn't surprise me to learn that someone is making a 32-bit uC with an MMU that nevertheless has a 32-level or smaller hardware call stack.
