Error creating Symmetric variables without string-names in 1.1.1.

[Johan-Gronqvist]

I am trying to create a symmetric variable (or matrix of variables) with JuMP 1.1.1 using the option to not create string names.

The following two work for me

model = Model(Hypatia.Optimizer)
@variable(model, [1:2, 1:2], Symmetric)

model = Model(Hypatia.Optimizer)
set_string_names_on_creation(model, false)
@variable(model, [1:2, 1:2])

but when combine the two options (symmetric and no string names)

model = Model(Hypatia.Optimizer)
set_string_names_on_creation(model, false)
@variable(model, [1:2, 1:2], Symmetric)

it seems to try to create a matrix from a string MethodError: no method matching (Matrix)(::String) with the stacktrace containing

I can reproduce. An elusive bug in JuMP! This is my fault in #2978. I'll take a look.
