Hello again :)

I think I know what causes the SEGV crash. As I have already mentioned the problem always occurs while using mysqldump and I could not repeat this using 'SELECT ... FROM ... INTO OUTFILE ...' from mysql console. This may require to have a larger tables in the database because all must be running at the same time. Also at least one table must have float field. My database has 15 tables with total direcotry size of 240MB.

Try this: /usr/local/mysql/bin/mysqldump -T /tmp/ --all --fields-terminated-by="~END~" test_db & /usr/local/mysql/bin/mysqldump -T /tmp/ --all --fields-terminated-by="~END~" test_db &

mysqld crashes every time on my FreeBSD 4.2-STABLE.

Here is the important part of gdb's 'back full'
