stream: read from beyond the head
@egmontkob
Submitted by Egmont Koblinger Link to original bug (#740347)
Description
Apply the attached patch (a single assertion that you don't try to read from beyond the head of a stream).
Start producing heavy output, and drag the scrollbar up-n-down crazily with the mouse. In about 10 second, you'll get a crash on that failing assertion.
