We prove that every locally compact non-discrete abelian group G contains a compact subset E such that A(E) - the restriction algebra of A(G) to E - admits spectral synthesis, although it contains a closed, regular, self-adjoint subalgebra which is isomorphic to an algebra of infinitely differentiable functions on [-1, 1]. We also give some general results concerning the failure of spectral synthesis in regular Banach algebras.
