I have a problem with a phantom "die" statement:

Use of uninitialized value in die at ./correct-<censored>-buch.pl line 114.
Died at ./correct-<censored>-buch.pl line 114.

However, this line does not contain a 'die', even though it used to. Currently it is: $update->execute(($autor, $titel, $verlag, $jahr, $ort, $auflage, $sprache, $einband, $seiten, $format, $stichwort, $sparteName, $lfdnr, $infotext, $preis_euro, $gewicht, $isbn)) or print "Fehler beim Aktualisieren von ISBN $isbn.\n";

I have tried reproducing the problem in a mini script, leaving the parameters for the update uninitialized or using a key for $isbn that does not exist. But not of that failed let alone caused the script to exit by a triggered "die" statement.

'$update' is defined as follows:

#!/usr/bin/env perl
use strict;
use warnings;
use DBD::mysql;
(...)
my $updateStatement =
"UPDATE `<censored>_buch`
SET
        `autor` = ?,
        `titel` = ?,
        `verlag` = ?,
        `jahr` = ?,
        `ort` = ?,
        `auflage` = ?,
        `sprache` = ?,
        `einband` = ?,
        `seiten` = ?,
        `format` = ?,
        `stichwort` = ?,
        `sparteName` = ?,
        `lfdnr` = ?,
        `infotext` = ?,
        `preis_euro` = ?,
        `gewicht` = ?
WHERE
        `isbn` = ?
LIMIT 1";
(...)
my $db = DBI->connect("DBI:mysql:database=<censored>;host=localhost;po
+rt=3306", "<censored>", "<censored>");
my $update = $db->prepare($updateStatement) or die ($DBI::errstr);
