OK, thanks for this information.

It's unfortunate that the source code for Amiga LhA is not free.
The m68k version can unpack it. Possibly they have applied a similar 'hack'.
Hacks are not nice but sometimes necessary.
Regarding point 1: the majority of archives would be 'Amiga' ones.
When you expect a UNIX archive, wouldn't you have a higher number of CRCs (and double decompress operations) than when expecting an Amiga archive?
