Did you test what is exactly leaking? I noticed a leak for output
formats. When write_trailer is not called then default values for string
options are leaking.
Your patch may cause a problem when some formats doesn't consider
possible calling read_close without read_header earlier.
It didn't review it deeply, so maybe it won't happpen, but my point is
if cleaning up options isn't enough?
