GREEDY_REALLOC takes a pointer to the real size, not the array-width as
argument. Therefore, our array is currently way to small to keep the seat
positions.
Introduce GREEDY_REALLOC0_T() as typed version of GREEDY_REALLOC and store
the array-width instead of array-size.

+ if (!GREEDY_REALLOC0_T(s->positions, s->position_count, pos + 1))
return;
