Subject: Don't try to serialize references.
X-Git-Tag: php-4.0.3RC1~29
X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=4b89b67d1cfd4e3dc28320335d02b880ee7bf4c8;p=php

Don't try to serialize references.

Circular references would otherwise kill PHP, as the serializer
would overrun the stack.
