possible compile_env! error

[gregors]

Elixir and Erlang/OTP versions

Erlang/OTP 27 [erts-15.2.7.2] [source] [64-bit] [smp:16:16] [ds:16:16:10] [async-threads:1] [jit:ns]

Elixir 1.19.2 (compiled with Erlang/OTP 27)

Operating system

Ubuntu

Current behavior

Moving from 1.19.0 to 1.19.2 I am now seeing compile time error where I didn't see one previously

** (Mix) the application :app has a different value set for key :currency_symbol during runtime compared to compile time. Since this application environment entry was marked as compile
time, this difference can lead to different behavior than expected:

I have removed both deps and _build but still receive this error.

Jumping back to 1.19.1 my project compiles without error. Also worth noting I see the same error on OSX.

Expected behavior

not see an error

Can you please provide a small application that reaproaduces the error? Thank you.

It seems to be my use of the "฿" value as a test case

It's worth noting I've compiled Elixir myself on Ubuntu, but the OSX install was via Brew.

[gregors]

as in MIX_ENV=test mix compile fails but mix compile is fine

Thanks @gregors for the repro!
I was able to pinpoint this commit: a8000f2, this is due to the removal of the chardata conversion (this is treated as iodata).
Will send a PR.
