internal error in native_compile

Hello,

I am experiencing a strange error when compiling with +native the following module:

----------------------------
-module(hipe_crash).
-export([f/6]).

f(A, B, C, D, E, L) ->
    lists:foldl(fun (X, P) ->
        AVar = case A of
            0 -> 1 / D;
            N -> N / (C - B)
        end,
        BVar = case E of
            atom1 -> 1.0;
            atom2 -> 0.8;
            _ -> E
        end,
        CVar = case X of
            atom1 -> 0.1 * AVar;
            _ -> 1.0
        end,
        P * BVar * CVar
    end, 1, L).
----------------------------

I couldn't restrict the code further. For example, the error does not happen without the atom2 case line for BVar.

With +native, I get:

                {hipe,'-finalize_fun_concurrent/3-fun-3-',4}]}

This is with an R14A OTP installation configured with --enable-native-libs.

Any idea?
