The attached SQL will fail on the x86_64 build of 5.0.13rc, but not on the x86 build.

$mysql weblog < just_cookies.sql
ERROR 126 (HY000) at line 115: Incorrect key file for table  './weblog/log_cookie_fragment.MYI'; try to repair it

How to repeat:
The attached file is atomically repeatable on my server, which is CentOS 4 + mysql-standard-5.0.13-rc-linux-x86_64-glibc23.

Thank you for a problem report. Sorry, but I was not able to repeat the crash you are writing about on the following x86_64 machine:

-bash-2.05b$ uname -a
Linux nocona.mysql.com 2.4.21-32.0.1.ELsmp #1 SMP Tue May 17 17:46:36 EDT 2005 x86_64 x86_64 x86_64 GNU/Linux
-bash-2.05b$ cat /etc/issue
Red Hat Enterprise Linux AS release 3 (Taroon Update 2)
Kernel \r on an \m

with 5.0.14-rc I built there myself (I note it is NOT 5.0.13-rc, but I have to verify with a current version in any case). Moreover, I see no real reasons for your test script to fail in any case. 

So, please, provide the additional information: your my.cnf content, any unusual messages from the error log and any ideas on why this problem can happen to you and how to repeat it.

After rather a lot of painful testing, this config item appears to be the culprit:

key_cache_block_size = 10240

This has been reproduced on multiple machines with various mysql.com distributed binaries.

Sorry, still can't repeat, neither on 32-bit with 5.0.16-BK (that is what you described too), nor on nocona. I've just recreated the table and inserted all the rows from your script:

mysql> select count(*) from log_cookie_fragment;
| count(*) |
|      106 |
1 row in set (0.00 sec)

mysql> select version();
| version()                  |
| 5.0.14-rc-nightly-20050919 |
1 row in set (0.00 sec)

mysql> show variables like 'key_cache%';
| Variable_name            | Value |
| key_cache_age_threshold  | 300   |
| key_cache_block_size     | 10240 |
| key_cache_division_limit | 100   |
3 rows in set (0.00 sec)

mysql> exit
-bash-2.05b$ uname -a
Linux nocona.mysql.com 2.4.21-32.0.1.ELsmp #1 SMP Tue May 17 17:46:36 EDT 2005 x86_64 x86_64 x86_64 GNU/Linux

with your key_cache_block_size...

So, please, give the information I asked about (your my.cnf content, all of it, any unusual messages from the error logs), as well as all the versions that demonstrates the described behaviour.

The same result (can't repeat the behaviour you described) with standard, published 5.0.13-rc, built from the sources on this nocona x86_64 platform. Just want you to know...
