If I use vi, then do search with '/', but don't enter a string, I get a segfault. This does not put the dut in a bad state. This could be a problem if a user is making changes to a file without saving, hits this bug and loses there data.
What platform is this? Please fill in proper host, target and build triplets. How did you configure vi? Paste your $ grep _VI .config thanks,
Seems to be fixed in last release. If you want the fix to be added to next 1.12.x stable release, backport the fix to 1.12.x and follow these instructions: http://busybox.net/fix.html
I found this bug in busybox 1.10.2, but the lowest version option is 1.12.x so I selected 1.12.x in the "Version" field.
Closing since it is fixed in released stable versions.
