This smells very much like a bug fixed upstream some years ago. lib/rfc1035.c has received quite many bugfixes over the years and I would recommend updating it to lastest Squid-2 upstream version minus the off_t/size_t changes (not relevant, part of another major cleanup). Regards Henrik
RHEL2 is no longer supported.
