    Description

      When running code with tiered support in schema_abort (from WT-9369) I am hitting a seg fault in the internal thread. It is processing a tiered FLUSH work unit. The entry->tiered structure is a valid dhandle it is not a valid tiered structure (the tiered structure is a superset handle of the dhandle).

      The bstorage field and other tiered related fields are all NULL.

      (gdb) p tiered->bstorage
      $3 = (WT_BUCKET_STORAGE *) 0x0
      

      The stack:

      (gdb) bt
