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);
}

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.
Actual result:
