I see that there's a previous assertion failure printed: /usr/bin/ld: BFD version 2.30-10.fc29 assertion fail elflink.c:14313 14308 void 14309 elf_append_rela (bfd *abfd, asection *s, Elf_Internal_Rela *rel) 14310 { 14311 const struct elf_backend_data *bed = get_elf_backend_data (abfd); 14312 bfd_byte *loc = s->contents + (s->reloc_count++ * bed->s->sizeof_rela); 14313 BFD_ASSERT (loc + bed->s->sizeof_rela <= s->contents + s->size); 14314 bed->s->swap_reloca_out (abfd, rel, loc); 14315 } Created attachment 1406243 [details]

Corresponding assembler input file
A couple of other IFUNC tests in the glibc test suite trigger this asserts. This is basically the same as BZ 1552056, except that it is the S390x that is affected this time. (In fact it turns out that the AArch64 target will also have this problem). I have created a patch to fix the problem, and applied it upstream: https://www.sourceware.org/ml/binutils/2018-03/msg00157.html I am going to backport this patch to Fedora and update this BZ once that is done. The patch is now in: binutils-2.29-14.fc27 binutils-2.29.1-22.fc28 binutils-2.30-12.fc29 Cheers Nick This message is a reminder that Fedora 27 is nearing its end of life. On 2018-Nov-30 Fedora will stop maintaining and issuing updates for Fedora 27. It is Fedora's policy to close all bug reports from releases that are no longer maintained. At that time this bug will be closed as EOL if it remains open with a Fedora 'version' of '27'. Package Maintainer: If you wish for this bug to remain open because you plan to fix it in a currently maintained version, simply change the 'version' to a later Fedora version. Thank you for reporting this issue and we are sorry that we were not able to fix it before Fedora 27 is end of life. If you would still like to see this bug fixed and are able to reproduce it against a later version of Fedora, you are encouraged change the 'version' to a later Fedora version prior this bug is closed as described in the policy above. Although we aim to fix as many bugs as possible during every release's lifetime, sometimes those efforts are overtaken by events. Often a more recent Fedora release includes newer upstream software that fixes bugs or makes them obsolete. Fedora 27 changed to end-of-life (EOL) status on 2018-11-30. Fedora 27 is no longer maintained, which means that it will not receive any further security or bug fix updates. As a result we are closing this bug. If you can reproduce this bug against a currently maintained version of Fedora please feel free to reopen this bug against that version. If you are unable to reopen this bug, please file a new report against the current release. If you experience problems, please add a comment to this bug. Thank you for reporting this bug and we are sorry it could not be fixed. |
