[erlang-questions] Bug ?!

[datacompboy]

Is that a bug of compiler?

-module(a).
-record(x, {a, b, c}).
-export([bug/1]).

bug(X) ->
  receive
    {msg, X#x.a} -> ok
  after 0 -> ok
  end.

We got "illegal pattern" on {msg, X#x.a}.
If we change code so:
bug(X) ->
  XA = X#x.a,
  receive
    {msg, XA} -> ok
  after 0 -> ok
  end.

it works. Is that bug of records compilation, or feature?!
