1. 必须在命令行中设置为要分析的进程打开用户堆栈信息：C:\Program Files\Debugging Tools for Windows (x64)>gflags.exe -iYourDebugProcess.exe +ust
2. 必须是Debug版本的进程
3. 设置好windbg的pdb路径，即symbol path
4. 利用windbg的AttachToProcess (貌似后面这个方案不行：在目标机器上产生转储文件（dump）然后用windbg分析）。
5. 利用!heap命令
示例：
0:032> !heap -s
NtGlobalFlag enables following debugging aids for new heaps:
stack back traces
