What steps will reproduce the problem?
(Какие операции/etc. вызывают проблему?)
1. Call u_CopyStr('') or u_CopyAnsiStr
This will result in a Access Violation (or SSIGEV)

What is the expected output? What do you see instead?
(Что ожидается в итоге? Что происходит
вместо ожидаемого?)
An empty string

What version of the product are you using? On what operating system? With
what compiler - Delphi/FreePascal?
(Какую версию используете? На какой
операционной системе? С каким
компилятором - Delphi/FreePascal?)
FreePascal 2.6.0 on Windows

Please provide any additional information below.
(Пожалуйста, предоставьте
дополнительную информацию ниже)
u_CopyStr is also called internally, for example when you call 
"key_BeginReadText('', 20)". Adding a 

if (len > 0) then
  System.Move(...)

check fixes the problem.
