segmentation fault pyswip with swipl 6.6.4 on Ubuntu 14.04

[y f]

Hi all,

I've been trying to use pyswip and no such luck. Installed using apt-get and linked libswipl.so to libpl.so. After the following commands:
$ python
$ from pyswip import Prolog
$ prolog = Prolog()
everything seems fine. But at
$ prolog.assertz("father(michael,john)")
I get "segmentation fault (core dumped)".

Tried installing from source 6.6.4 and 7.2.3 using the following in the source folder:
$ ./configure --prefix=/usr --enable-shared
$ make
$ sudo make install

This doesn't appear to create a shared library. No libswipl.so or libpl.so.

Help appreciated!
