Erlang 19 Compilation Error

I'm getting a compilation error with a project that uses combine.

Elixir 1.2.6
Erlang 19

== Compilation error on file lib/combine/parsers/text.ex ==
** (FunctionClauseError) no function clause matching in :elixir_errors.handle_file_error/2
    (elixir) src/elixir_errors.erl:186: :elixir_errors.handle_file_error("Elixir.Combine.Parsers.Text", {:beam_validator, {{Combine.Parsers.Text, :float_impl, 1}, {{:call, 4, {:f, 50}}, 43, {:multiple_match_contexts, [{:x, 0}, 1]}}}})

could not compile dependency :combine, "mix compile" failed. You can recompile this dependency with "mix deps.compile combine", update it with "mix deps.update combine" or clean it with "mix deps.clean combine"

Doing it outside the project kills things too :(

I cloned this and played around with it a bit.

On Elixir 1.3.0 and Erlang 19.0 I get

== Compilation error on file lib/combine/parsers/text.ex ==
** (CompileError) Elixir.Combine.Parsers.Text: function float_impl/1+43:
  Internal consistency check failed - please report this bug.
  Instruction: {call,4,{f,137}}
  Error:       {multiple_match_contexts,[{x,0},1]}:

    (stdlib) lists.erl:1338: :lists.foreach/2
    (stdlib) erl_eval.erl:670: :erl_eval.do_apply/6

but if I change the #{line} at

combine/lib/combine/parsers/text.ex

Line 574 in f5d1169

    
           %{state | :status => :error, :error => "Expected valid float, but was incomplete `#{extracted}`, at line #{line}, column #{col + extracted_len}"}

to #{state.line} it compiles.

Damn, this is an interesting one. @adamkittelson can you make a PR with your fix so I can merge it and release a fix? I'll get it done tonight one way or the other.

Closing this as a duplicate of #17 for now
