critical problem in www/squirm

[krym at sklug.sk]

hi, 

i have instaled new fbsd 5.3 server with squid and squirm.
(squid-2.5.9_3, squirm-1.23_2). it seems to working fine but after each
request squirm processes died on signal 11
strip:
Mar 24 09:14:28 zeon kernel: pid 10656 (squirm), uid 100: exited on
signal 11 (core dumped)
Mar 24 09:14:28 zeon kernel: pid 58065 (squirm), uid 100: exited on
signal 11 (core dumped)
Mar 24 09:15:40 zeon kernel: pid 58067 (squirm), uid 100: exited on
signal 11 (core dumped)

if i run /usr/local/bin/squirm from shell and i put Ctrl+D, i become
every time the following lines:
squirm in free(): error: chunk is already free
Abort trap (core dumped)

on many requests it consumes a lot of system resources and may crash the
system (on 256ram it makes about 170m of swap and about 10 minutes i was
not able to log into the system)
i have uploaded some of coredumps here:
