Malloc fail will result in SEGSEV

[harm-smits]

On get_next_line.c line 66, you allocate an empty string. If the malloc fails, you then call ft_strchr on the empty string you allocated. Since you don't check whether the string is valid in ft_strchr, you will try and access the index of a NULL pointer, thus causing a segmentation fault.
