Thank you for this bug report. Unfortunately, the threaddump is invalid, as it states that #8 0x0000000000a1e968 in pagecache_unlock_by_link (pagecache=0x1aaf930, block=0x1aaf320, lock=PAGECACHE_LOCK_READ_UNLOCK, pin=28009498, first_REDO_LSN_for_page=3003604992, lsn=35, was_changed=1 '\001', any=0 '\0') at ma_pagecache.c:3013 #9 0x0000000000086745 in ?? () #10 0x0000000001aaf320 in ?? () #11 0x0000000001aaf930 in ?? () #12 0x00000000b3076000 in ?? () #13 0x0000000000a36dd8 in _ma_set_share_data_file_length (share=0x1abe5a0, new_length=0) at ma_state.c:550 which is impossible (_ma_set_share_data_file_length() is a very short function which does not call pagecache_unlock_by_link()).

such bad thread dump makes me wonder about memoy corrution. Could you please re-run the test with mysqld under Valgrind?

Actually Vemund provided feedback, and the problem seems to be gone now (could be explained by some recent fixes by Monty and Serg for bugs corrupting memory).
