In a UBSAN debug build, the comparisons with next_mrec_end are made with index->online_log's head/tail members' block ptr with a sort buffer size offset (1048576). The logic that flows though to this point means that even srv_sort_buf_size above a null pointer wouldn't contain the value of next_mrec_end. As such this is a UBSAN type fix where we first check if the head.block / tail.block is null before doing the asserts around this debug condition. This would be required for the assertions conditions not to segfault anyway. |
