if the function `fts_read` get a return value of NULL and the malloc from `fts->fts_cycle.state = malloc (sizeof *fts->fts_cycle.state)` (Line 62 in fts_cycle.c) is NULL, the pointer `fts->fts_cycle.state` will still keep 0 before the free operation `free (sp->fts_cycle.state);` (Line 159 in fts_cycle.c), leading to free of invalid address.
I don't see a problem, since 'free (0)' is valid and does nothing.
