nextCellCallback 读取带合并单元格的文件时报 Segmentation fault

版本: PHP 7.2.24 (Docker: php:7.2.24-fpm-buster) xmlwriter 1.3.1 (pecl 方式安装)

Excel结构大致如下:

+------------------+
|      Header      |
+------+-----+-----+
|  K1  |  K2 |  K3 |
+------------------+
|  V1  |  V2 |  V3 |
+------+-----+-----+

读取代码:

<?php
$excel  = new \Vtiful\Kernel\Excel(['path' => '/home/staff']);
$excel->openFile('data.xlsx')
    ->nextCellCallback(function ($row, $cell, $data) {
        var_dump($data);
    });

估计可能错在 kernel/read.c 243行的 strlen(value) 调用, value 可能是 null 或者非字符串 https://github.com/viest/php-ext-xlswriter/blob/33ff16f8935ecbc24490a3c8d202d44ca82b3bee/kernel/read.c#L243
