In .dovecot.sieve I have:

require ["regex", "fileinto", "include"];

include :personal       ".forward.sieve";

if anyof
(
address :matches "From"
[
        "email at somedomain.com"
],
address :matches "To"
[
        "myemail at mydomain.com"
],
header :contains "Subject"
[
        "some subject"
]
)
{
       # many commented rules
        keep;
        stop;
}
else {
       many commented rules
        keep;
        stop;
}

in .forward.sieve there are above hundred redirects

redirect "test.1 at domain.pl";
redirect "test.2 at domain.pl";
...
redirect "test.120 at domain.pl";
redirect "test.121 at domain.pl";

In debian etch deliver stoping redirectict about 80-90 address and dying 
with signal 11. In debian lenny deliver redirect to all addresses but 
also dying.

I run deliver through gdbhelper in this way

dovecot   unix  -       n       n       -       -       pipe
    flags=DRhu user=vmail:vmail argv=/usr/lib/dovecot/gdbhelper 
/tmp/deliver.sh -d ${recipient} -f ${sender}

and in /tmp/deliver.sh

#!/bin/sh
sleep 1
exec /usr/lib/dovecot/deliver $*
