Description:
CHECKSUM TABLE myisam_table

returns different results depending on whether checksum is live or calculated

How to repeat:
see myisam.test

CHECKSUM TABLE t1 QUICK
CHECKSUM TABLE t1 EXTENDED

should return the same number
(actually all CHECKSUM TABLE commands in the test should return
the same number or NULL)

Do you have any plans to fix this in the near future? I'm asking because as far as I can see, I can not work on bug #8552 until this bug is fixed.

I doubt that I can get at it in the near future unless its priority is raised.
