In process_last_np_surv_region, we set the special_sweep_p flag when we don't have a region after next_region = heap_segment_next (alloc_region) is null together with some other conditions that is irrelevant here.

Later, in process_remaining_regions, we assert that heap_segment_next_rw (current_region) == 0. I assume that it is checking the same thing, which is okay.

But special_sweep_p is a PER_HEAP_ISOLATED member, which means if one heap has that condition, it will set the flag for other heaps. On the other heaps, it is possible that the corresponding next_region is not null, thus triggering the assert.

Changing the flag from PER_HEAP_ISOLATED to a PER_HEAP member solved the issue.

In process_last_np_surv_region, we set the special_sweep_p flag when we don't have a region after next_region = heap_segment_next (alloc_region) is null together with some other conditions that is irrelevant here.
Later, in process_remaining_regions, we assert that heap_segment_next_rw (current_region) == 0. I assume that it is checking the same thing, which is okay.
But special_sweep_p is a PER_HEAP_ISOLATED member, which means if one heap has that condition, it will set the flag for other heaps. On the other heaps, it is possible that the corresponding next_region is not null, thus triggering the assert.
Changing the flag from PER_HEAP_ISOLATED to a PER_HEAP member solved the issue.
