I tried the php version from cvs and it seems to fix the test I
provided.  However, if I remove '$err = $query->errorCode();' from the
test case, it will core dump again, though the execution still appears
to complete.

Description:
------------
Core dump on PDO error.

PDO error code if checked before execute is 'HY093'.

Reproduce code:
---------------
<?php
  //use actual database, user and password where applicable
  $dbh = new PDO('pgsql:host=127.0.0.1;dbname=foo', 'foo', 'foo');

  $query = $dbh->prepare('INSERT INTO table (varA, varB, varC) VALUES (
:varA, :varB, :varC );');

  $query->bindValue(':foo', 'foo');
  $query->bindValue(':varC', 'foo');
  
  $err = $query->errorCode();
  echo "$err\n";

  echo "you will see this.\n"; flush();
  $query->execute();
  
  /*
    CRASH POINT

    You will see only output that has been flushed.

    If running on the command line you will also see something like
this:

    *** glibc detected *** malloc(): memory corruption: 0x16987018 ***
    Aborted (core dumped)

  */

  echo "you won't see this.\n"; flush();
?>

Expected result:
----------------
HY093
you will see this.
you won't see this.

Actual result:
--------------
HY093
you will see this.
*** glibc detected *** malloc(): memory corruption: 0x16987018 ***
Aborted (core dumped)
