## Steps To Reproduc... -
- We don't need to allocate a new page in gc_sweep_finish_size_pool.
It can be allocated when needed. -
- Some size pools may not have any pages/slots, so total_slots is 0. This
causes a divide-by-zero in the calculation. This commit adds a special
case to catch the case when total_slots is 0 and returns the number of
pages for heap_init_slots. -
- If the size pool has no or few pages/slots, then min_free_slots will
be a very small number (or even 0). Then the heap won't be eligible to
grow, causing GC thrashing or infinite loops. -
- Size pools with no pages won't be swept so gc_sweep_finish_size_pool
will never be called on it, but gc_sweep_finish_size_pool must be called
to grow the size pool. -
- Depending on alignment, the last bitmap plane may not used. Then it will
appear as if all of the objects on that plane is unmarked, which will
cause a buffer overrun when we try to free the object. This commit
