When I try execute star solution, where the executable size is larger than 1 GB on PC with 2GB of RAM memory, there is always message "Segmentation fault". If I try it on the PC with 1GB of RAM, there is no problems, but the solution is too slow. Where is the mistake?

If the 2 GB machine is running Linux, trying compiling with a capital y option, i.e.

starlink -Y

Yes, there is running Linux. The option -Y don´t solve the problem. There is still mesage "Segmentation fault" I use Star CD v 3.150A and RedHat Linux 7.3 machine.

It's not something simple like a limit problem I suppose? Try the limit command:

% limit
