UndefinedBehaviorSanitizer crash in SQLite3 BLOB fseek(PHP_INT_MIN, SEEK_END)

Description

The following code:

<?php

$db = new SQLite3(':memory:');

$db->exec('CREATE TABLE test (id TEXT, data BLOB)');

$stmt = $db->prepare('INSERT INTO test (id, data) VALUES (:id, :data)');
$stmt->bindValue(':id', 'a', SQLITE3_TEXT);
$stmt->bindValue(':data', 'TEST TEST', SQLITE3_BLOB);
$stmt->execute();

$row = $db->querySingle("SELECT data FROM test WHERE id='a'", true);

$stream = $db->openBlob('test', 'data', 1); 
var_dump(fseek($stream, PHP_INT_MIN, SEEK_END));

Resulted in this output:

php-src/ext/sqlite3/sqlite3.c:1193:47: runtime error: negation of -9223372036854775808 cannot be represented in type 'zend_off_t' (aka 'long long'); cast to an unsigned type to negate this value to itself

But I expected this output instead:

Inizia in ext/sqlite3/sqlite3.c alla riga 1193, usando lo script PHP fornito per riprodurre il fallimento di UndefinedBehaviorSanitizer. Controlla la gestione di fseek per PHP_INT_MIN con SEEK_END e aggiungi o aggiorna il test dello stream SQLite3 pertinente in modo che la chiamata termini senza comportamento indefinito e restituisca -1.
