In Issue SMTorg#571, I encountered a bus error. Using AddressSanitizer, I traced the error to a negative memory index caused by a 32 bit signed integer overflowing the bounds and requesting memory from a negative index. Swap out `int` for `long` so that more total memory can be addressed and allow larger problem sizes.
