GCC 6.2 with  {{--enable-default-pie}}, which is enabled e.g. in the Debian Testing package, breaks HiPE (and Dialyzer, if it uses HiPE):

{code:erlang}
{'EXIT',{badarg,[{hipe_bifs,patch_call,
                            [1103888528,94502719669968,[]],
                            []},
                 {hipe_unified_loader,patch_call_insn,3,
                                      [{file,"hipe_unified_loader.erl"},{line,508}]},
                 {hipe_unified_loader,patch_bif_call_list,4,
                                      [{file,"hipe_unified_loader.erl"},{line,494}]},
                 {hipe_unified_loader,patch_call,5,
                                      [{file,"hipe_unified_loader.erl"},{line,485}]},
                 {hipe_unified_loader,patch,5,
                                      [{file,"hipe_unified_loader.erl"},{line,462}]},
                 {hipe_unified_loader,load_common,4,
                                      [{file,"hipe_unified_loader.erl"},{line,215}]},
                 {hipe_unified_loader,load_native_code,3,
                                      [{file,"hipe_unified_loader.erl"},{line,111}]},
                 {code_server,try_load_module_2,6,
                              [{file,"code_server.erl"},{line,1131}]}]}}
{code}

Compiling Erlang/OTP with CFLAGS and LDFLAGS set to "-no-pie -fno-pie" solves the problem. The bug affects current stable version 19.1.5 and the current master branch ([214aba4|https://github.com/erlang/otp/commit/214aba4]).

Actually, it affects all versions.

As replied in the erlang-questions mailing list, adding {{no-pie}} in the flags is probably the easiest and safest solution to this problem.

If there are no objections, can somebody from the OTP team (Sverker?) please do that?

Maybe it would be good to add it in the maint-19 branch, as some distributions are already affected:
