[initCompute] Failed to allocate XXXXX indices.

Describe the bug

` pcl::PassThroughpcl::PointXYZ pass;
pass.setInputCloud(cloud);

// 设置要过滤的坐标轴和范围
pass.setFilterFieldName("z");
pass.setFilterLimits(0.0, 10.0);
pass.filter(*cloud_cut)

执行该段代码时候遇见此问题，参考https://blog.csdn.net/weixin_44338329/article/details/130293396，很多人遇见该问题至今并未解决。我已经测试过很多版本了。

Your Environment (please complete the following information):

• OS:win10
• Compiler: vs2022
• PCL Version：pcl1.10.1，pcl1.13.1，pcl1.14.1，

我采用vs2017，c++11，pcl1.9.1运行都正常，采用高版本c++17和cpl皆出现该问题

hello，I've tested VS2017, C++11, and PCL 1.9.1, and everything runs fine. However, when using higher versions like PCL 1.10.1, PCL 1.13.1, and PCL 1.14.1,c++17， the problem occurs.

@wangzhenlin123 The error message comes from here: https://github.com/PointCloudLibrary/pcl/blob/master/common/include/pcl/impl/pcl_base.hpp#L164
3721543846 indices need almost 14 GB of memory (RAM). Did you check if that much was available when you run the program? Is it correct that your point cloud has 3721543846 points (3.7 billion)?

Thank you for your reply. In fact, there are only 52928 data points, so there aren't as many as indicated. I'm also puzzled why it shows so many.

@wangzhenlin123 Do you use CMake? If not, there are two things that might cause this problem:

• You build your code in Release configuration, but link the PCL Debug libraries, or the other way around, you build your code in Debug configuration, but link the PCL Release libraries
• You set incorrect architecture options (SSE, AVX), which lead to wrong alignment of data structures. These have to match the ones used within PCL

CMake automatically handles all of this, which is why we recommend using it.
