BoundsError generate_tex_elementes of a subscript with Julia 1.9.0-beta2 and OrdinaryDiffEq.jl

[jaakkor2]

With Julia v1.9.0-beta2 started as julia +beta --startup-file=no, OrdinaryDiffEq v6.37.0, MathTexEngine v0.5.4, I see

using OrdinaryDiffEq
using MathTeXEngine
generate_tex_elements(L"$a_{00}$")

errors as

ERROR: BoundsError: attempt to access Tuple{Tuple{TeXChar, GeometryBasics.Point2{Float64}, Float64}, Tuple{TeXChar, GeometryBasics.Point2{Float64}, Float64}, Tuple{TeXChar, GeometryBasics.Point2{Float64}, Float64}} at index [4]

Without using OrdinaryDiffEq the example works fine. Julia v1.8.5 seemed to work fine.

Simplified

using NonlinearSolve
using MathTeXEngine
generate_tex_elements(L"$a_{00}$")

[jaakkor2]

A bit more simplified

using LoopVectorization
using MathTeXEngine
generate_tex_elements(L"$a_{00}$")

[Kolaru]

This is a problem with LoopVectorization (or one of its dependency):

julia> a = []
Any[]

julia> push!(a, 2, 3, 4)
3-element Vector{Any}:
 2
 3
 4

julia> using LoopVectorization

julia> push!(a, 2, 3, 4)
ERROR: BoundsError: attempt to access Tuple{Int64, Int64, Int64} at index [4]

Keeping it open until it is solved upstream.

Fixed in Julia 1.9.0-beta3, worked around in LoopVectorization 0.12.147.
