Hi Peter,

do you have by chance any idea, why this is going wrong?

Maybe a hint would be good, how I can debug this?

Thanks

I suspect that it's due to the return type (Void)..IIRC aldor deals
with this by returning an empty Tuple.. Fix is to modify hashCode.boot
someplace..

I can't test this quickly, but it might work to do:
EQL(retCode, $VoidHash) => hashCombine(32236, hash)
hashCombine(retCode, hashCombine(32236,hash))

replacing lines 58&59. This is totally untested as I don't have a
working (or up-to-date) fricas build at the moment.

Looks to work ok..

Yes. I could actually already have confirmed that last night, but it was
too late.

Didn't first work by just changing hashCode.boot. But after
recompilation FriCAS+libaxiom.al from scratch. It is seemingly doing the
right thing.

Thanks a lot.

I'll try to get it into FriCAS soon.
