New Comment:
This could be the same bug as #35552.
I couldn't reproduce the issue, but did spot some code that might cause
something like this to happen.
Please try the next snapshot dated after this message to see if that
nailed it.

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:
