plperl crash with Debian 6 (64 bit), pl/perlu, libwww and https

Hi

I have been helping some people to debug a SIGALARM related crash
induced by using pl/perlu http get functionality

I have been so far able to repeat the crash only on Debian 64 bit
computers. DB create script and instructions for reproducing the crash
attached

The crash is related to something leaving begind a bad SIGALARM handler,
as it can be (kind of) fixed by resetting sigalarm to nothing using perl
function

REATE OR REPLACE FUNCTION reset_sigalarm() RETURNS VOID
LANGUAGE plperlu
AS $_X$
$SIG{ALRM} = 'IGNORE';
$_X$;

( unfortunately this hoses deadlock detection and statement_timeout )

Environment where this crash does happen:

Debian GNU/Linux 6.0 - x86-64
openssl 0.9.8o-4squeeze1
postgresql-9.0 9.0.4-1~bpo60+1
postgresql-plperl-9.0 9.0.4-1~bpo60+1
libwww-perl 5.836-1

Postgresql is installed from backports

It does not happen on 32 bit ubuntu
