Been struggling to figure out why accesses to these struct fields are causing memory allocations. Here is my test code: module AllocationsTest struct SubStruct a::Float64 b::Float64 end struct AllocationsStruct arr::Array{SubStruct} end function make() subStructArr = Array{SubStr…

[image] dellagd: struct AllocationsStruct arr::Array{SubStruct} end Array{T} is not a concrete type. Array{T,1} (or equivalently Vector{T}) is. You are missing this type parameter, so the field is abstractly typed. In your second, parametric version you almost get there except you write …
