Paul, I like this feature very much. Actually, I did some POC one year ago but I did finalize it.
In my POC, I could use EBP to tack the stack frame on IAS32 arch. But for x64, I tried to use �Ckeepexceptiontable flag to explain stack frame from the debug section of image. I may workson MSFT toolchain, but it did now work well for GCC toolchain. I think Eric could help to verify MSFT for your patch. If it works well, that’s will be great! Say again, I like this feature!!!:-) Thanks!

I've attached a file to show you how the trace would look like. Thanks!
