I observed a regression when updating from SymEngine.jl v0.8.7 to v0.9.0. The following code works well in the old version
julia> using Pkg; Pkg.activate(temp = true); Pkg.add(name = "SymEngine", version = v"0.8.7")
julia> using SymEngine
julia> a, b, c = symbols("a b c")
(a, b, c)
julia> a * [b, c]
2-element Vector{Basic}:
a*b
a*c
julia> a * 1//3 * [b, c]
2-element Vector{Basic}:
(1/3)*a*b
(1/3)*a*c
However, it fails as follows in the new version:
julia> using Pkg; Pkg.activate(temp = true); Pkg.add(name = "SymEngine", version = v"0.9.0")
julia> using SymEngine
julia> a, b, c = symbols("a b c")
