Bug description:pdo_dblib segmentation fault when iterating MONEY values
Description:
------------
Fix for bug 51213 released into 5.2.14 and 5.3.3 causes segmentation fault
when an SQL query attempts to read MSSQL MONEY type columns, or aggregates
of those column types.
Problem appears to be invalid val->data pointer passed to spprintf() call
at line 174 of dblib_stmt.c
Oddly, the patch attached to bug 51213 works properly, but is not the same
as what was comitted to the code base.
In the patch attached to 51213, val->data is properly emalloc'd some memory
before any sprintf()-type of operation is performed.
Test script:
---------------
// On a table containing a MONEY (field named "amount");
$sql = "SELECT SUM(amount) FROM table";
$rs = $pdo->query($sql, PDO::FETCH_OBJ);
foreach($rs as $row) {
var_dump($row);
}
Expected result:
----------------
Expected to see rows dumped from table.
Actual result:
--------------
Segmentation fault.
