The result was empty (no rows returned), and there was a read from 0x00000000 when (I think) mssql_fetch_assoc() executed. Reproduce code: --------------- I had no time to record the exact code, but it was something like this: $q=mssql_query("select * from table", $db, 50); do { while ($row=mssql_fetch_assoc($q)) { ... } } while (mssql_fetch_batch($q)>0); the table was empty. I then prepended if (mssql_num_rows($q)>0) and everything was fine. Expected result: ---------------- nothing, the table was empty :) Actual result: -------------- a crash because of reading 0x00000000 ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=31818&edit=1
