ID: 35620 User updated by: humbads at alum dot mit dot edu Reported By: humbads at alum dot mit dot edu Status: Open Bug Type: ODBC related Operating System: Windows XP SP2 PHP Version: 5CVS-2005-12-10 (snap) New Comment:
The same crash occurs if the code is simply within a function, rather than a class. Furthermore, the same crash occurs if another data source is used, e.g. SQL Server. myfunction(); function myfunction() { $odbc = new PDO("odbc:Driver={Microsoft Visual FoxPro Driver};SourceType=DBF;SourceDB=C:\\"); $query = "SELECT * FROM invoice"; $result = $odbc->query($query); } Previous Comments: ------------------------------------------------------------------------ [2005-12-10 08:24:07] humbads at alum dot mit dot edu Description: ------------ php-cgi.exe crashes with an access violation when using PDO ODBC to run a simple query as given below. The code runs without error if not enclosed in a class. It also runs without error if the query is run without saving the return value in $result. The stack trace indicates a crash when destroying the implicit prepared statement. Reproduce code: --------------- $mc = new MyClass; class MyClass { function MyClass() { $odbc = new PDO("odbc:Driver={Microsoft Visual FoxPro Driver};SourceType=DBF;SourceDB=C:\\"); $query = "SELECT * FROM invoice"; $result = $odbc->query($query); die("happy"); } } Expected result: ---------------- It should not crash when returning the result, or when running from within a class.
