Conflicting Sandwich clues cause infinite loop #87

When a single row or column contains 2 conflicting Sandwich clues, the solver gets stuck in an infinite loop. Here is an example f-puzzles link.

Interestingly, when the same 2 sandwich clues are places on row 1 (top row) then the solver finishes correctly with no solution. Correct behaviour f-puzzles link.
