Here is a bug...

[Jasper Taylor]

$ gprolog
GNU Prolog 1.2.13

| ?- length(P,3000), P = [97 | Q], prefix(Q,P), format_to_codes(B, [126,115],
[P]).



Fatal Error: Segmentation Violation
B = $

The first three clauses in this demo are merely to create a list of 3000 "a"s, 
and that is what you get when you do them on their own. However when you then 
go format_to_codes even just citing this string, a segmentation error occurs!

...and I want to use strings _much_ longer than 3000 chars...

Hoping my effort in submitting this helps to improve the quality of Free 
Software worldwide...
