Bug#704802: plperl crashes immediately on kfreebsd

[Peter Eisentraut <petere@debian.org>]

Package: postgresql-plperl-9.1
Version: 9.1.9-1
Severity: important

Creating a plperl function on kfreebsd (amd64) immediately crashes the
PostgreSQL server in the plperl.so module.  You can see this either by
running the built-in regression tests (should probably be done during
the build anyway) or by running the tests from
t/020_create_sql_remove.t in the postgresql-common package.

Everything else works, including all the other procedural languages
(Python, Tcl).

I can also reproduce this problem with PostgreSQL Git master, so it's
not specific to the packaging.  The actual problem might be somewhere
down the stack (libperl etc.).
