Bug 12899 – slices don't work in memory window

In VS, Debug->Windows->Memory shows a memory view. Usually you can paste pointers in the address box and view the memory at that pointer. This doesn't work for slices. Instead, it shows the memory of the slice structure itself, not what it points to. Additionally, mySlice.ptr doesn't work in the debugger either. I can't work out how to get the pointer from a slice in expression evaluation. Slices appear as a struct with a single 'length' element, which you can view by pressing the '+' (expand) button next to the slice. But the expression mySlice.length doesn't work either.

As far as I can see, showing just the length value happens for function arguments only. I remember there has been some special treatment to arguments regarding x64 debug info, it seems the visualizer cannot deal with this. To display the raw struct of array arguments without visualizer, you can use "mySlice,!" in the watch window.
