Thanks for answers. I still didn't solve the problem, but it gave me

Seems like a plausible explanation, but I don't quite understand how
linux finds shared libraries, and, most important, why it can't find
shared libraries only when using 'screen ./fooint2.exe'. It seems
that I have LD_LIBRARY_PATH set in my .bashrc:
I still get [screen is terminating] if I run
screen /bin/sh -c fooint2.exe
I also tried
screen /bin/sh -c /home/kreso/prog/fooint2.exe
but doesn't work.

I also thought of that, so I changed that program so that it doesn't
execute commands, but prints them instead. Then I copy-pasted the
lines that program printed, and it worked fine.

Thanks for sugestion, but this actually won't help because
eventually I have to call screen from a complex program that can't
be substituted with a script.
But... maybe if I write a script, and then call that script with
system(), maybe that would work. Well, I will certainly try.
