reproducing the coredump

(deinstallation- If you`ve already build most of the PHP5-extensions from ports:

rename the extensions .so dir to reinstall
ping# mv /usr/local/lib/php/20060613/ /usr/local/lib/php/20060613_bogus

then

cd /usr/ports/lang/php5-extensions

ping# make deinstall && make config 

enable recode

ping# make clean && make install && rehash

ping# cat /usr/local/etc/php/extensions.ini | grep "recode"

extension=recode.so

ping# php -v
