ifx_pconnect() crashes when called without username/password in function call AND no default values in php3.ini.

- informix (informix client sdk 2.40.uc1-1 for sun solaris 2.6)

./configure --prefix=/opt/$APACHE --with-apxs=/opt/$APACHE/bin/apxs --with-config-file-path=/opt/$APACHE/conf --enable-track-vars --with-informix=/opt/informix --with-mysql=/opt/mysql-3.22.27 --with-ldap=/opt/openldap-1.2.9

apache-1.3.12 built with:
mod_ssl 2.6.2
openssl 0.9.5

GDB backtrace:

I guess SAFE_STRING(p) should get that but does not!
