Din cate imi dau eu seama, din programul meu nu
 este niciun leak de memorie pentru ca folosesc un singur vector pt exec (pt "./executabil_care_nu_exista") pe care-l eliberez.

Am trimis tema si am observat ca si la testul 5 apare aceeasi eroare (pe calculatorul meu nu aparea). Totusi, testul trece. Problema se pare deci ca este la rularea exec cu parametru o comanda care nu exista (la testul 5 este cd /new/york/san/francisco).
