Fwd: connect to SQL server 2005

Hi,

SQL Server version : SQL 2005
FreeTDS version (or snapshot date, if not a release) : freetds-0.82
which client library you are using : unixODBC (libtdsodbc.so)
what language or Perl module, as appropriate, you're using : php (
built in odbc module)
your client OS and hardware architecture (red hat x64)

I can connect through isql and tsql fine.  but having trouble when
connect using php.  I have made sure that I set the mbstring in
php.ini correctly to take UTF-8. but looks like the 4th
tds_process_tokens()   get halt in the middle the process and did not
receive the packet I should receive and when I run the php script, it
gets "segmentation fault"

can someone help please?

Thanks

Jun
