Hi again, I managed to get GCC5.2.0 building against binutils 2.26: $ ~/.fighome/runtime/gcc/5.2.0-2/bin/ld.gold --version GNU gold (DRW-internal-build 2.26.20160125) 1.11 Copyright (C) 2015 Free Software Foundation, Inc. This program is free software; you may redistribute it under the terms of the GNU General Public License version 3 or (at your option) a later version. This program has absolutely no warranty (FWIW I had to install the patch in this bug: https://gcc.gnu.org/bugzilla/show_bug.cgi?id=66259 to get it to build in-tree). Sadly the problem remains: Dump of assembler code for function std::_List_node<std::function<void ()> >::~_List_node(): 0x0000000000762240 <+0>: push %rbp 0x0000000000762241 <+1>: mov %rsp,%rbp 0x0000000000762244 <+4>: sub $0x10,%rsp 0x0000000000762248 <+8>: mov %rdi,-0x8(%rbp) 0x000000000076224c <+12>: mov -0x8(%rbp),%rax 0x0000000000762250 <+16>: add $0x10,%rax 0x0000000000762254 <+20>: mov %rax,%rdi 0x0000000000762257 <+23>: callq 0x0 0x000000000076225c <+28>: nop 0x000000000076225d <+29>: leaveq 0x000000000076225e <+30>: retq End of assembler dump. Any thoughts on what flags I might give to gold to try and track this down? I tried -Wl,--debug,all and there didn't seem to be all that much debug information.
