I am not agree. I take _another program_ which work fine during ~2 year
with previouse mysql version (mysql-3.23.44 for example).
And I send dump from this program.
Why I interested libmysqlclient_r?
I have a program, which try to connect to mysql twice.
But the second connection freeze in mysql_real_connect.
I use libmysqlclient.so (mysql-3.23.42 & FreeBSD-4.4RC)
I try to upgrade to mysql-3.23.49 and use mysqlclient_r on test
computer and have many problems (I write about their before).
But now I attach to working process which freese and see:
(gdb) bt

Under FreeBSD gethostbyname is not thread-safe
And there is no thread-safe gethostbyname_r
(function exist but not thread-safe)
Are mysql know about this!!!
