Hi,
I believe i've found a problem in MySql. Here are some test's i've made in
3.22.27 x86( also tested on v3.22.32 - latest stable, although i didn't
debug it, just tested to see if crashes ).
On one terminal:
<quote>
spike:/var/mysql # /sbin/init.d/mysql start
Starting service MySQL.
Starting mysqld daemon with databases from /var/mysql
done
spike:/var/mysql #
</quote>
On the other terminal:
<quote>
jroberto@spike:~ > mysql -p -e 'select a.'`perl -e'printf("A"x130)'`'.b'
Enter password:
(hanged..^C)
</quote>
On the first terminal i got:
<quote>
spike:/var/mysql # /usr/bin/safe_mysqld: line 149: 15557 Segmentation fault
nohup
$ledir/mysqld --basedir=$MY_BASEDIR_VERSION --datadir=$DATADIR --skip-lockin
g "$@" >>$err_log 2>&1
Number of processes running now: 0
mysqld restarted on Fri Jan 12 07:10:54 WET 2001
mysqld daemon ended
</quote>
gdb shows the following:
