Tak to na końcu. W końcu program po podaniu argumentów robi zupełnie co innego niż jak go włączysz bez argumentów.

Skąd masz ten program? To binarka czy ręcznie kompilowałeś?

Nie znam się za bardzo, ale mi to wygląda na problem z zapisem do pamięci.

To binarka.

To jest preinstalowany system na zdalnym serwerze dedykowanym.

Nie mam do niego fizycznego dostepu.
