- The function build_table_filename() builds up a string unconditionally using the forward slash as a path separator. Later, when the string is searched for FN_LIBCHAR by the set_up_table_before_create() function, a null pointer is returned that is finally used by strlen in the append_file_to_dir() function which causes the crash.
