Not that useful without debug symbols, but at least shows the crash is in dblib:

Description:
------------
If you attempt to use getColumnMeta() on a prepared but not yet executed
PDOStatement, using the dblib driver, you get a segmentation fault.
FreeTDS library version 0.82-7
Test script:
---------------
<?php
$pdo = new PDO('dblib:host=SERVICE;dbname=xxx','xxx','xxx');
$result = $pdo->prepare('SELECT * FROM users');
$meta = $result->getColumnMeta(1);
Expected result:
----------------
I would expect to get the column metadata just as it as after execution, as in
this code sample:
<?php
$pdo = new PDO('dblib:host=SERVICE;dbname=xxx','xxx','xxx');
$result = $pdo->prepare('SELECT * FROM users');
$result->execute();
$meta = $result->getColumnMeta(1);
var_dump($meta);
Gives:
array(8) {
'max_length' =>
int(8)
'precision' =>
int(0)
'scale' =>
int(0)
'column_source' =>
string(4) "mode"
'native_type' =>
string(7) "unknown"
'name' =>
string(4) "mode"
'len' =>
int(8)
'pdo_type' =>
int(2)
}
Actual result:
--------------
Segmentation fault
Don't have debugging symbols or gdb on the machine sorry :(
