Introduced very recently, likely in #56880

julia: /source/src/julia.h:1319: jl_array_ptr_ref: Assertion `i < ((*(size_t*)jl_svecref(((jl_datatype_t*)(((((jl_taggedvalue_t*)((char*)(a) - sizeof(jl_taggedvalue_t)))->header) & ~(uintptr_t)15)))->parameters, 1)) == 1 ? (((jl_array_t*)(a))->dimsize[0]) : (((jl_array_t*)(a))->ref.mem->length))' failed.
