segfault

Hi, I got a segfault in gprolog (compiled from source yesterday):

* The type of machine you are using (use uname -a under Unix).
Linux zenwalk 2.6.16.16 #1 PREEMPT Thu May 18 21:20:55 CEST 2006 i686
pentium2 i386 GNU/Linux

* GNU Prolog version (use gprolog --version).
Prolog top-Level (GNU Prolog) 1.3.0

* The operands given to the `configure' and the output of the configuration
None

* The complete text of any files needed to reproduce the bug.
None

* The precise commands we need to type to reproduce the bug.

| ?- father(X) = X.

[gprolog went into infinite loop (this isn't the bug)]
[I typed Ctrl-c]

Prolog interruption (h for help) ? h
   a  abort        b  break
   c  continue     e  exit
   d  debug        t  trace
  h/? help

* A description of what behavior you observe that you believe is incorrect.
