Hello,
The source code of hipe:load/1 shows that it's supposed to work with
sticky modules, but in fact, it's not.
load(Mod, BeamFileName) when is_list(BeamFileName) ->
Architecture = erlang:system_info(hipe_architecture),
ChunkName = hipe_unified_loader:chunk_name(Architecture),
case beam_lib:chunks(BeamFileName, [ChunkName]) of
{ok,{_,[{_,Bin}]}} when is_binary(Bin) -> do_load(Mod, Bin, Bin);
% <-- here, Bin is the native chunk
Error -> {error, Error}
end.
then do_load goes like this :
do_load(Mod, Bin, WholeModule) ->
...
case WholeModule of
...
BinCode when is_binary(BinCode) ->
case code:is_sticky(Mod) of
true ->
% this is where we end up for sticky modules such as lists (hipe.erl,
line 917)
%% We unpack and repack the Beam binary as a workaround to
%% ensure that it is not compressed.
{ok, _, Chunks} = beam_lib:all_chunks(WholeModule), % <--
WholeModule is still the native chunk above (line 928).
{ok, Beam} = beam_lib:build_module(Chunks),
%% Don't purge or register sticky mods; just load native.
code:load_native_sticky(Mod, Bin, Beam);
...
end
end.
The crash happens line 928 :
** exception error: no match of right hand side value {error,beam_lib,
{not_a_beam_file,<<131,108,0,0,0,11,104,2,107,0,5,51,46,
55,46,51,98,2,132,8,38,97,8,97
,...>>}}
in function hipe:do_load/3
Indeed, it's not a beam file, it's a beam native chunk.
