Insert problem with PHP and MSSQL

[wxdqz]

When I use mssql_query with the query "select * from tablename", it works correctly.

But when I want to execute an 'INSERT INTO' statement (or UPDATE or DELETE
the script stop at the mssql_query execution although the new row is inserted correctly.

And, if I try to execute a wrong request, It stops the script too (no return)

In the apache error_log file i have the message
"exit signal Segmentation fault (11)"

My configuration:
- MS2000 with a SQL Serveur Database
- Linux with Apache, PHP, php-sybase_ct, module for accessing database

Please Help !!!!!

Thanks
