Error description
Running a stored procedure that is enabling PDQPRIORITY and querying a fragmented table, may result in bad block header memory corruption type assertion failures. Here's a same bad block assertion: 14:55:18 Found during mt_shm_free 1 14:55:18 Pool '44' (0x47fc2040) 14:55:18 Bad block header 0x4842d028 blk-64 000000004842cfe8: 00000000 00000000 00000000 00000000 ........ ........ 000000004842cff8: 00000000 00000000 10009000 02010000 ........ ........ 000000004842d008: 00000000 00000000 0000011f 00000008 ........ ........ 000000004842d018: 000000cd 00000433 6820cf46 00000000 .......3 h .F.... blk+64 000000004842d028: 00000000 00000000 4700d901 00005b0c ........

If PDQ is removed from the SPL, the memory corruption assertion is no longer seen.
