# 3683 LIKE Operator Can Cause AV If Pattern Being Searched For Is Much Larger than Search Column/Value

As of few recent EDB releases I'm seeing AV's when using LIKE operator:

(stack from client application, generally useless)
EEDBError: ElevateDB Error #9999 Access violation at address 005A32F6 in module 'DB.exe'. Read of address 064A0000
edbcomps TEDBQuery.CreateCursor
edbcomps TEDBQuery.CreateHandle
edbcomps TEDBDataSet.OpenCursor
edbcomps TEDBDBDataSet.OpenCursor
DB TDataSet.SetActive

There is a problem with function edbstring.LikeString which calls CompareStrings with invalid FirstStringLength argument.
