Description

I get invalid reads while testing ffplay with attached iff ilbm (ham8) file under amigaos, so it would be good to check if the same happen under valgrid - "ffplay a4000t_ham8.iff"

the problem seems to disappear when I comment out two lines in decode_ham_plane32() function

There are still invalid writes while testing with FFplay (Peter's valgrid log).
