            Bug ID: 15256
           Summary: ash treats SIGWINCH as typed newline
           Product: Busybox
           Version: unspecified
          Hardware: All
                OS: Linux
            Status: NEW
          Severity: normal
          Priority: P5
         Component: Other
          Assignee: unassigned at busybox.net
          Reporter: elly at elly.town
                CC: busybox-cvs at busybox.net
  Target Milestone: ---

As the summary says. If you start ash, then resize the window it's in, ash acts
as though you had typed a blank line. To reproduce this without resizing a
window, you can start ash in one terminal then send SIGWINCH to it from another
terminal; ash reacts by re-displaying the prompt on a new line as though an
empty line had been typed.

This was introduced some time between 1_35_stable and 1_36_stable, maybe by
12566e7f9b5e5c5d445bc4d36991d134b431dc6c.
