Greetings,

After successfully installing version 0.64 of FreeTDS (and several previous 
offerings), I've come across a strange error.  Our systems are mostly SuSE 
Linux 10 systems, though we have a few newer Debian installs for good 
measure.  The problem is similar across all these servers.

When I compile FreeTDS 0.64 from source, one test fails:

-------------------BEGIN------------------------------
Trying cs_config with CS_USERDATA

Testing CS_SET/GET USERDATA with char array
Testing CS_SET/GET USERDATA with char array
Testing CS_SET/GET USERDATA with int
PASS: cs_config
All rows read, this may not occur.
cancel.c: Check asynchronous called ct_cancel()
More results?...
do_fetch retrieved 10000 rows
do_fetch() returned: 0
More results?...
FAIL: cancel
---------------------END----------------------------

When I do the installation routine for DBD::Sybase 1.08, several fail, 
although some failures are to be expected, per the DBD::Sybase README.freetds 
file:

----------------------BEGIN---------------------------

---------------------------END----------------------


OS: SuSE Linux 10
Remote DB: SQL Server 2005
FreeTDS Version: 0.64
DBI version: 1.59
DBD::Sybase Version: 1.08

In the freetds.conf file (contrived for privacy):
[sqlserver2005]
        host = sqlserver2005.hostname.com
        port = 1433
        tds version = 8.0

The problem can be recreated using the following contrived table:

-----------BEGIN----------------------------------------
CREATE TABLE tds_test (
   id int,
   dt datetime,
   yr int
)
------------END----------------------------------------

And the following perl code.  Take special note that I'm trying to use undef, 
which should translate to NULL per the DBI specification.  All of the above 
fields are nullable (id, dt, yr).  I was simply trying to make a contrived 
case that could be easily replicated.

------------BEGIN-----------------------------------------
#!/usr/bin/perl -w

use strict;
use warnings;
use DBI;
use Data::Dumper;

my $dbh = DBI->connect(
    'DBI:Sybase:server=sqlserver2005',
    'username',
    'password',
);

my $sth = $dbh->prepare( q{
    UPDATE tds_test
    SET dt = ?, yr = ?
    WHERE id = ?
} );

$sth->execute( undef, undef, 110684130 ) || die DBI->errstr;
------------END------------------------------------------

The error produced is:

------------BEGIN------------------------------------------
out of memory for rpc row!DBD::Sybase::st execute failed: Server message 
number=8178 severity=16 state=1 line=2 server=sqlserver2005 text=The 
parameterized query '(@P1 varchar(80),@P2 varchar(80),@P3 varchar(80))
    UPDATE tds' expects the parameter '@P1', which was not supplied. at 
rpc_problem.pl line 24.

-------------END-----------------------------------------

When I update to one of the more recent FreeTDS snapshots, e.g. 
freetds-0.65.dev.20070910, without recompiling DBD::Sybase, the error 
disappears.  But then I can't recompile DBD::Sybase, without the following 
errors:

After pouring through documentation on perlmonks, FreeTDS mailing list, and 
DBD::Sybase's lists, I've come up dry.  In fact, searching for the error "out 
of memory for rpc row" on google only yields references to the FreeTDS code, 
but not how to fix them.  Any thoughts?
