PHP Bug Type: ODBC related
Bug description: access violation on odbc 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:
--------------
