[erlang-bugs] enif_make_double returns invalid term for 'nan'

[Heinz Nikolaus Gies]

When enif_make_double gets a nan value passed as the double argument it returns a invalid term, this term can neither be printed (via the fmt*) functions nor can it be deserialized by binary_to_term when serializing it the following binary is generated:

6> io:format("~p~n", [term_to_binary(V)]).
<<131,99,110,97,110,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0>>

V is the double returned by enif_make_double
