Hi,
Just change the user id's and database in the scripts to match your
mssql database and run the scripts. The script is self contained
otherwise. I was only able to duplicate the problem with ADOdb and PEAR
DB. Straight mssql_* works fine. So a one-liner is a bit difficult.
Regards, John

any chance you can cut your test script down to just a single line or
two to prove this?

When doing testing with ADOdb and PEAR DB, the following scripts crash
PHP (when the delete statement is executed) with an illegal memory
reference at 0xffffffff. I tried to duplicate the problem with native
mssql functions, but could not.
While tracing through in ADOdb, I found that the crash occurs during
the PHP return statement, and not within mssql code. Perhaps some form
of subtle stack/data corruption.
Thanks, John Lim
