aria: background thread crashes in make_lock_and_pin

Details

    Description

      During a generic DML stress test of Aria tables, after a while a debug build crashed a few times with the same stack. There is no exact testcase to trigger a problem.

      Version: '5.5.30-MariaDB-debug' Source distribution
      		 
      Thread 18:
      		 
      Invalid read of size 8

      Address 0x10 is not stack'd, malloc'd or (recently) free'd

      The line of code in question is a DBUG_ASSERT.

      2587      DBUG_ASSERT(block->hash_link->block == block);
      		 
      (gdb) p block
      		 
      $1 = (PAGECACHE_BLOCK_LINK *) 0x27dbafa0
      		 
      (gdb) p block->hash_link
      		 
      $2 = (struct st_pagecache_hash_link *) 0x0
