Problem with spidering

[tomjed]

I have

PHP 5.1.2
MySQL 4.1.16

When I try to index site

php -e -f spider.php http://www.domain.com
27235: old priority 0, new priority 18

Spidering in progress...
-----------------------------
SITE : http://www.domain.com/
Exclude paths :
- @NONE@

Wait...
Bus error (core dumped)

I have this error with version 1.8.9-rc1 .
I don't have this problem with version 1.8.8.
This problem occurs of course with web interface.
I need 1.8.9 to index UTF sites.

I don't have any idea what's wrong and I don't know how to solve this problem, it's too little information, maybe there are information in php.core, but I don't know it's structure.

Any suggestions ??
