Description of problem:
There is a problem with the mysql_upgrade program where it is failing to update tables created with mysql v4 such that they appear corrupted can can't be accessed within v5.1


Version-Release number of selected component (if applicable):
mysql-5.1.32-1.fc11

How reproducible:
Not sure - but many people have seen this.  There are reproducible test cases available

Steps to Reproduce:
1. Create a database in mysql v4
2. Update mysql to 5.1
3. Run mysqlcheck on the database
  
Actual results:
Errors such as:

warning  : Table is marked as crashed
warning  : Size of indexfile is: 1975296      Should be: 1572864
error    : Found key at page 180224 that points to record outside datafile
error    : Corrupt
Error    : Incorrect key file for table 'Clone_hit'; try to repair it
error    : Corrupt

Repair table (even with use_frm) can't fix this, neither can isamchk.  Apparently it requires a dump from the old verion, completely deleting the files under /var/lib/mysql (apart from the mysql tables), and then a restore to get things working again.

This could potentially cause big problems.


Expected results:
Tables are upgraded properly from older versions.

Additional info:
There is an upstream report of this, which suggests that this is fixed in v5.1.35 but I've not been able to verify that this solves the problem and the bug page isn't exactly chock full of reports that it works.  The upstream bug is at:
