cfg.c: redundant second assignment of bb_copy = NULL in free_original_copy_tables()

[Prathamesh Kulkarni]

Hi,
There appears to be a redundant second assignmeent bb_copy = NULL in
free_copy_original_tables(). I suppose it should be
bb_original = NULL instead ?
I found this mentioned on a blog "Bugs found in gcc with help of PVS studio":

Thanks,
