An issue was discovered in Schism Tracker through 20190722. There is an integer underflow via a large plen in fmt_okt_load_song in the Amiga Oktalyzer parser in fmt/okt.c.
The product subtracts one value from another, such that the result is less than the minimum allowable integer value, which produces a value that is not equal to the correct result.
