% Regression test for bug #244: when asked for all solutions (with G12/FD)
|
|
% this model did not produce the solution (i = 0, b = false). The problem
|
|
% was that the flattening of the reified array lookup in the constraint was
|
|
% incorrect. We were emitting (in pseudcode):
|
|
%
|
|
% (i = i' <-> i <= size(arr)) /\ i >= 1
|
|
%
|
|
% rather than
|
|
%
|
|
% (i = i' <-> i (i >= 1 /\ i <= size(arr)))
|
|
%
|
|
% i' is the fesh index variable.
