When viewing the results of destructive operations for Array, using the hovering tooltips, the array is modified irreversibly. Consider the following code: a = [1, 2, 3] puts a.shift Hovering the mouse over "a" and "shift" in the second line "destroys" the array: see the tooltip for "a", then for "shift", then for "a" again, and so on, until the size of "a" is 0.
This is relative to, might the same as, issue 101120 (which is even worse). This will have to be fixed rather in the backend in the debug-commons rubyforge project. Very likely not in 6.0 time frame. I think that even mature Java debugger do this. But in Ruby it could be easier to prevent this. Hopefully will have time for this after 6.0. Thanks for the report.
