DataStructures version

I run julia from a clean environment, e.g.
docker run -it julia:1.10
add DataStructures to the environment

(@v1.10) pkg> status
Status `~/.julia/environments/v1.10/Project.toml`
  [864edb3b] DataStructures v0.18.19

It says v0.18.19
I test for a bug that should be fixed

using DataStructures
struct A1 end
struct A2 end
c = CircularBuffer{A1}(10)
try push!(c, A2()); catch end; 
@assert isempty(c)

It fails

The error should be fixed since v0.18.12.
Clone the repo, checkout v0.18.12, there should be a test in tests/test_circular_buffer.jl named "Issue 754", but it's not there? Is the tag wrong?

I download the archive of the same release (0.18.12) from github, it's the same (no test named "Issue 754", what version are these archives?

run a diff between 0.18.12 .. 0.18.15 but it's way too short?

The registry has versions up to 0.18.19, but this repo only has tags up to 0.18.15?

Am I haunted? 👻

it's because of #865 i guess
