not throw error but crash when assign an expression to array

[acsofie]

environment:

Debian ⛬  julia/1.5.3+dfsg-3

[[SymEngine]]
deps = ["Compat", "Libdl", "LinearAlgebra", "RecipesBase", "SpecialFunctions", "SymEngine_jll"]
git-tree-sha1 = "6cf88a0b98c758a36e6e978a41e8a12f6f5cdacc"
uuid = "123dc426-2d89-5057-bbad-38513e3affd8"

uuid = "3428059b-622b-5399-b16f-d347a77089a4"
version = "0.8.0+0"

use:

using SymEngine
@vars a
b=zeros(2)

now the type of a is Basic and the type of b is Array{Float64,1}. if we assign a Basic to an element of b, it throw an error.

julia> b[1]=a
ERROR: ArgumentError: symbolic value cannot be evaluated to a numeric value
Stacktrace:

This is acceptable. However, if use an expression, then

julia> b[1]=a+1

signal (6): abort

julia crash completely. This situation may need an ArgumentError.

I can't reproduce this.

@isuruf which version of julia and SymEngine you use? I downloaded it from the official debian apt repo. Maybe debian problam?
