It seems like you are observing this crash on kFreeBSD OS. Well, me or
any of my colleague is not having this OS hence, i can't comment on
that. But, we do have Ubuntu OS (another Debian based OS) and I am not
seeing any server crash here as well,

As i mentioned in my earlier email, could you please delete the Utilc.
and SPI.c files from src/pl/plperl directory, rebuild the source code
and then let us know the results. Thanks.
