Hello all,

I downloaded PHP 5.1 beta and tried to compile it with:

'./configure' '--prefix=/home/jay/php5_1' '--disable-cgi' '--enable-cli'
'--with-xml' '--with-libxml-dir=/home/jay/php/lib'
'--with-config-file-path=/home/jay/etc/php5' '--without-pear'
'--enable-debug'

PHP 5.1 (unlike PHP 5.0) seems to need libxml2.

It compiles okay, but when I do ./php --version it seg faults.

Here is the GDB output. I was hoping someone had insight into what is
causing it.

Thanks in advance,

- Jay
