Albo wyskoczyłeś poza zakres tablicy albo wręcz przekazałałeś zdeallokowany pointer wskazujacy w kosmos. > ==4215== Conditional jump or move depends on uninitialised value(s) > ==4215== by 0x424ABA: is_subdir_of_any(std::__cxx11::basic_string<wchar_t, std::char_traits<wchar_t>, std::allocator<wchar_t> >, std::vector<std::__cxx11::basic_string<wchar_t, std::char_traits<wchar_t>, std::allocator<wchar_t> >, std::allocator<std::__cxx11::basic_string<wchar_t, std::char_traits<wchar_t>, std::allocator<wchar_t> > > > const&) (common.cpp:476) > ==4215== by 0x452EC6: obfuscator::remember_identifiers(std::__cxx11::basic_string<wchar_t, std::char_traits<wchar_t>, std::allocator<wchar_t> >, identifiers_vector*, bool, bool) (obfuscator.cpp:1440) Tu podobnie. Sprawdź co robisz w tych linijkach, które podpowiedział valgrind. Przy okazji: kompilowałeś program z -O0? Takie błedy często się ujawniają po wyłączeniu optymalizacji.
