ERROR: StackOverflowError:

while saving array using JLD2, Error occurs. It seems to be due to Measurements.jl package.
How to solve this issue?

Code:

using Measurements, JLD2
a = Array{Complex{Measurement}, 2}
@save "file_path" a

Return:

[JackKenney]

Was there a fix for this?

[giordano]

I believe it had been fixed two years ago by JuliaIO/JLD2.jl#196
