Dear Prof Daniel Diaz

I would like to inform you about the following bug. When doing
the following steps, i.e. writing the empty string to
an aliased file:

       ?- open('tin.txt', write, _, [alias(tin)]).

       ?- write(tin,'').

I get an application crash. I don't work from a C development 
environment, so I only see the crash dialog but no
further dump information.

See attachment. The problem happens with GNU Prolog 1.4.0.

Best Regards
