[freetds] freetds - invalid cursor state

Hi guys, we have to find some solution.
 
We have perl script using DBD::ODBC to connect to MSSQL using unixODBC driver and FreeTDS. When we execute stored procedure and this stored procedure is executing another stored procedure with raiserror or print functions we get invalid cursor state error.
 
i.e.:
CREATE PROCEDURE [dbo].[dummyproc] as
RAISERROR('test', 0, 0)
return 0
 
CREATE PROCEDURE [dbo].[testproc] as
select GETDATE()
exec dummyproc
select GETDATE()
return 0
 
This happens ONLY when we try to fetch results from second getdate() function.
i.e.:
my $query = 'exec testproc';
my $sth   = $dbh->prepare($query);
$sth->execute || die "Error running query $query";
while ( my $d = $sth->fetchrow_arrayref ) {
    print Dumper $d; #should return first getdate()
}
while ( my $d = $sth->fetchrow_arrayref ) {
    print Dumper $d; #should return second getdate()
}
 
We’re using:
Old perl 5.8.8.
DBD::ODBC version 1.45
unixODBC 2.3.1 (also tried newest 2.3.4.)
FreeTDS 0.91.dev.20110409RC1 (also tried FreeTDS 0.95.81)
 
In case we use Easysoft database driver instead of FreeTDS the error does not appear.
When I call out the procedure from tsql error does not appear.
 
The log using latest FreeTDS can be found here:

The unixODBC log (not sure it will help) can be found here:
http://jezecek.dyndns.org/odbc.log
 
I would really really appreciate if you can let me know what to focus on.
Thank you for any hints& supprt from you.
 
Regards,
JJ
