This is problem, xterm has properly size as you can see on picture 
kdbg-ncurses-BAD.jpg in my first post.
But ncurses get this COLS=80 & LINES=24. When i try debug, this values is 
receiving via _nc_getenv_num() for LINES and COLUMNS. There is problem. In getting 
this enviroment values. If I read values from ioctl there is every OK.
