Using --erl +A crashes iex

This command line

iex --erl +A 20 -S mix

crashes iex with an erl_crash.dump file on Ubuntu Precise with otp_19.1 and Elixir 1.3.4. Any readme’s on where I should start to figure this out?

On my macbook this command works just fine.

Please try again with iex --erl "+A 20" to make sure that the “20” is passed through as well. In your example only +A is passed to erl, while iex tries to understand 20 on itself.

Thanks that worked. Doh!
