 If you have a non-free version of Visual Studio, you can save a minidump via

 (<100KB), which contains information about the state of your process.

+As with the Visual Studio IDE, you can attach WinDbg to a running Vim process.

+At this point, choose Symbol File Path on the File menu, and add the folder

+source file at the point of the crash. Using the View menu, you can examine
+the call stack, local variables, watch windows, and so on.

+If WinDbg is your postmortem debugger, you do not need to attach WinDbg to
