gdb shows the fault here:
0x00400610 <+126>: lea-0x3fffe5b7(%rip),%rax#
0xc0402060
=> 0x00400617 <+133>: movl $0x14,(%rax)
That offset looks like a relocation overflow. Is gold trying to relax the
reference and doing it incorrectly? `--no-relax` doesn't help. The code looks
the same with and without the option.

[Bug gold/25034] gold creates incorrect executable with large arrays
https://sourceware.org/bugzilla/show_bug.cgi?id=25034 --- Comment #1 from David Greene --- Here is the original reference generated by gcc: movqx@GOTPCREL(%rip), %rax movl$20, (%rax) So it does look like gold is trying to relax the GOT reference to an LEA. -- You are receiving this mail because: You are on the CC list for the bug. ___ bug-binutils mailing list bug-binutils@gnu.org https://lists.gnu.org/mailman/listinfo/bug-binutils

https://sourceware.org/bugzilla/show_bug.cgi?id=25034 --- Comment #2 from David Greene --- Also note that bfd locates x below bigarrays.

This would have worked: - elfcpp::Elf_types<32>::Elf_Addr value; - value = (psymval->value(object, 0) -- target->got_plt_section()->address()); - Relocate_functions<32, false>::rel32(view, value); + typedef typename elfcpp::Swap<32, false>::Valtype Valtype; + Valtype* wv = reinterpret_cast(view); + Valtype addend = elfcpp::Swap<32, false>::readval(wv); + Valtype value = (psymval->value(object, addend) +- target->got_plt_section()->address()); + elfcpp::Swap<32, false>::writeval(wv, value); However, that looks very much like a pcrel32 using object/psymval, thus elfcpp::Elf_types<32>::Elf_Addr reladdr; reladdr = target->got_plt_section()->address(); Relocate_functions<32, false>::pcrel32(view, object, psymval, reladdr); -- You are receiving this mail because: You are on the CC list for the bug. ___ bug-binutils mailing list bug-binutils@gnu.org https://lists.gnu.org/mailman/listinfo/bug-binutils
