Excel 2010无法打开由PHPExcel创建的特定尺寸的xls文件

我们在我们的生产环境中使用PHPExcel已有4年多了，直到上周Excel 2010 & 2103无法打开PHPExcel生成的许多xls文件之一。我们得到的错误是Excel 2010无法打开由PHPExcel创建的特定尺寸的xls文件

错误：“Excel在文件中发现不可读的内容。是否要恢复此工作簿的内容？如果您信任此工作簿的源，请单击”是“。。

我们尝试修复并浏览其他我们发现的建议，但都没有成功。

生成许多文件后，我们至少能够一致地重现此问题。虽然它看起来很奇怪，但在Windows 7 &上运行的Excel 2010 & 10无法打开由phpExcel生成的6914K-6977K文件大小之间的任何文件。

我们无法找到任何解决方案或者Excel 2010/2013无法打开这些文件的原因。我们错过了什么吗？在此先感谢您的任何建议。

我们正在使用...

PHPExcel：1.8 网络服务器：Apache的/ 2.2.15（Unix的）& PHP 5.3.3在Red Hat

示例代码运行重现该问题。

试图改变这一点：

$objWriter = PHPExcel_IOFactory::createWriter($objPHPExcel, 'Excel5');

要这样：

$objWriter = new PHPExcel_Writer_Excel2007 ($objPHPExcel);

和改扩建的.xls到的.xlsx
