How about _you_ check this issue instead of brushing aside?
This bug is reproduced with ANY versions of PHP (5.1.6 - 5.2.4)

You report the bug with version 5.2.4, yet you seem to be using
5.1.6?!
How about you try with 5.2.4 first?

Description:
------------
$dbh = PDO('mysql:...',...);
$dbh->exec("SET some_var='value';SET names 'utf8'");
$dbh->query("SELECT NOW()");
# Error: Cannot execute queries while other unbuffered queries are
active. ...
PDO::MYSQL_ATTR_USE_BUFFERED_QUERY doesn't help.
I found that in mysql_handle_doer() multi-results aren't freed.
I'm not a MySQL C API professional, but this patch seems to solve this
problem:
