Please describe exactly what actions triggered the bug and the precise symptoms of the bug:
I opened two windows using C-x 3, and set the width of the right windows to a really small value (to be more precisely, it can display 50 characters per line). Then on the left line I run some command like M-x align<TAB>, as a result, the right window will be used as minibuffer and display auto-completion list. The bug is that, the list comes with all '\' on the right most and just cannot stop printing, and does not response to my control. In program 'top' I can see the CPU% of this emacs process is 100%.
I now can reproduce bug with the above operations. Under ArchLinux, in a bash terminal with screen 4.00.03.
