opcache used_memory reports negative value

<?php
                var_dump(opcache_get_status()['memory_usage']);
?>

Reports a negative value for used_memory.

Image is from a VDS system with opcache.memory_consumption=1GB and several sites.

But issue was reproduced within the following environment:

• PHP 8.3
• shared hosting server with PHP-FPM
• two sites with individual opcache.memory_consumption settings
• first site: 128M
• second site: 256M
• global settings in plesk: 256M

Second site reports correct values, but first site, with lower settings reports negative value for "used_memory"

Changing both sites to dedicated PHP-FPM fixes the issue, but in the default config it fails.

未指定源文件或测试。首先，在使用共享 PHP-FPM 池和不同 opcache.memory_consumption 设置的 PHP 8.3 上复现 opcache_get_status()['memory_usage']；将报告的值与专用 PHP-FPM 进行比较。在共享配置中 used_memory 保持有效且非负即表示完成。
