Regression: Packer detected in 3.10 but not 3.11

[Sembiance]

The attached SPLIT.COM.zip and RVQBT15K.COM.zip files are identifed with 3.10 code compiled from a git snapshot on 2025-05-07:

$ diec SPLIT.COM 
COM
    Packer: Packer[by B. Vorontsov]
$ diec RVQBT15K.COM 
COM
    Packer: Packer[1997 by JES //CORE]
$ diec --version
die 3.10

But they do not identify with 3.11 code compiled from a git snapshot on 2025-12-15:

$ diec SPLIT.COM 
COM
    Unknown: Unknown
$ diec RVQBT15K.COM
COM
    Unknown: Unknown
$ diec --version
die 3.11
