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:

=ERROR REPORT==== 22-Jul-2010::18:17:53 ===
<HiPE (v 3.7.6)> Error: [hipe:867]: ERROR: {function_clause,

global_groups_removed,1}]}

With +native +'{hipe, [verbose]}', I get:

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

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

Any idea?

Confirmed. You don't need --enable-native-libs, an R14A built without
that option fails in the same way.

You can work around it by adding the HiPE option no_inline_fp.
