近期在使用PCL库的过程中碰到了程序崩溃的问题，花了两三天的时间一直在解决该问题。
环境配置：
Windows11 + PCL 1.12.1 + VTK 9.1 + VS2019
爆出的问题：
在Memory.h文件的下述代码处爆出问题
/** internal Frees memory allocated with aligned_malloc. */
EIGEN_DEVICE_FUNC inline void aligned_free(void *ptr)
{
#if (EIGEN_DEFAULT_ALIGN_BYTES==0) || EIGEN_MALLOC_ALREADY_ALIGNED
std::free(ptr);
#else
handmade_aligned_free(ptr);
#endif
}

internal Frees memory allocated with aligned_malloc翻译过来应该是，内部释放使用aligned_malloc分配的内存。在VS输出窗口说是
HEAP[CircleTest.exe]: Invalid address specified to RtlValidateHeap( 0000025861220000, 00000258612B29D0 )
CircleTest.exe 已触发了一个断点。
针对这个问题，有人提到一个可能原因
在不同模块（工程）之间传递 C++ 类，而这两个模块用了不同的运行时库（Runtime Library）设置。
例如：EXE 模块调用 DLL 模块里传递 C++ 类的函数，但 DLL 模块使用静态链接（Release 是 Multi-threaded (/MT)、Debug 是 Multi-threaded Debug (/MTd)）方式编译，而 EXE 模块使用动态链接（Release 是 Multi-threaded DLL (/MD)、Debug 是 Multi-threaded Debug DLL (/MDd)）方式编译。
可以对比这两个模块的工程属性 - C/C++ - Code Generation - Runtime Library，看看设置是否一样，如果不一样要改成一样的。
但是经过检测，DLL和EXE工程的运行时库时一致的

这个说法跟我的情况倒是一样的，因为我也是两个工程，一个工程用于封装成dll，另一个工程中调用这个dll工程中封装的C++类。
针对该问题，还看到一种处理方法，就是用更低版本的VS，更改平台工具集。

甚至还有一种可能就是Debug和Release版本错乱。
关于他人的针对于DLL和EXE的运行时库不一样的解决方法

但是比较玄学的是，一模一样的代码，在别人电脑上不会崩溃。由此，开始怀疑是不是PCL库CMAKE出问题，只不过过去将近一年的使用没有发现罢了。于是果然卸载了PCL1.12.1，并选用AllInOne的方式重新安装PCL，这次不自己手动cmake。
结果，崩溃的问题还是出现。
此处先插入一条PCL库的下载地址，为了快捷和方便以及不想遇到各种麻烦直接选exe一键安装比较省事。

于是，开始思考是不是栈区太小，于是使用VS开始手动扩大栈区大小，默认是1MB，改到了100MB，结果还是不行。

后面重装了VS2019 也重装了PCL1.11.1，又装了PCL1.12.1，还是报同样的问题。开始怀疑是不是Win11的问题，后面干脆将整个工程拷贝到别人电脑上（也是win11），最终证明没问题。
后面按照同事的配置，一步步重新配置了一遍，问题好像得到了解决。
最初的PCL的系统环境变量如下：

现在的环境变量：

从上图可以看出，甚至同时配置了PCL1.11.1和1.12.1但是没有出问题，且第三方库只添加了VTK的路径。
还有个第三方库OpenNI2，这个一键安装就会自动添加上去，都不需要自己手动添加。

包含目录配置：

以上是目前PCL1.12.1的全部配置，问题消失。相对比发现，其实系统环境变量变了，其余的应该是都没有进行本质上的改动。但不确定是否是系统环境变量引起的。
