The testcase of BUG#39210 is grammar file maria_stress.yy; I just got the same assertion with maria_dml_alter.yy.

Monty, please don't look at it now. It may just be due to pagecache_read(PAGECACHE_LOCK_LEFT_UNLOCKED) not waiting for write-locks to be gone, thus full table scan may be reading an inconsistent page, hence the assertion because it finds unexpected content. Sanja will fix the page cache, so I assign this bug to him for now.
