There are two things happening when initially compiling and later on updating to a new iana tz data version: 1. parsing the IANA data files into time zone periods; 2....

Maybe you can link here then: https://hexdocs.pm/elixir/1.12/DateTime.html#module-time-zone-database

1. You can reproduce the problem every time consistently? 2. What if you replace: ```elixir polymorphic_embeds_one :channel, types: [ sms: MyApp.Channel.SMS, email: MyApp.Channel.Email ], on_type_not_found: :raise, on_replace: :update ``` by...

Yeah I'm able to test that out later. Full-time jobs suck your time:( What if you add the atoms you use in `:types` at the top? ```elixir :sms :email ```

Are you saying that you have an atom `:foo`, anywhere, and that when you run `:erlang.binary_to_existing_atom("foo", :utf8)` an error is raised?

Ok so the problem is not specific to `PolymorphicEmbed`? 1. You have an atom `:foo` (not related to `PolymorphicEmbed`) 2. You call `:erlang.binary_to_existing_atom("foo", :utf8)` (not related to `PolymorphicEmbed`) 3. An...

Ok so why do we have this behavior? It can create you problems with other libs similarly. I think it's worth asking the Elixir community. The cause? The impact? What...
