In schema.c line 116, (ss->size * 2) will not be large enough to hold the new
string if (ss->pos + l) >= ss->size + 1). To correct this I made the following
change to eliminate segment faults.

                while (ss->pos + l >= ss->size-1) {
                        ss->size *= 2;
                }
