file_in is initialized with stdin. When opening it, a failure is indicated by the NULL value assigned to file_in. The application then tries to close the NULL file descriptor as it is not equal to stdin which gives a segmentation fault. This patch adds a check if the file descriptor is NULL and does not try to close it if this is the case.
