Well, as Steve Langasek explains above, there is a lot of ocaml code
that shows sigbus error on sparc with ocaml 3.09.0... I am not really
sure this bug is only mldonkey bug (maybe it should be assigned to
ocaml... ).

I don't think also, tigertree bug is a well known one...

Really unknown error ;-)

Yes, maybe, i will reassign the bug to the package ocaml, so you'll have
to follow the indication of the ocaml maintainer...

Kind regard
