From ce5aecf87372749a5ec511f218956756aa185d0f Mon Sep 17 00:00:00 2001 From: Alan Modra Date: Mon, 27 May 2019 10:29:22 +0930 Subject: [PATCH] Another generic ELF target assertion failure After fixing the ld-elf/pr22836-1a segmentation fault we run into an assertion failure due to the generic ELF target not removing empty SHT_GROUP sections. Avoid that. * elf.c (bfd_elf_set_group_contents): Exit on zero size section. --- bfd/ChangeLog | 4 ++++ bfd/elf.c | 3 ++- 2 files changed, 6 insertions(+), 1 deletion(-) diff --git a/bfd/ChangeLog b/bfd/ChangeLog index 3f7f174..18bed06 100644 --- a/bfd/ChangeLog +++ b/bfd/ChangeLog @@ -1,5 +1,9 @@ 2019-05-27 Alan Modra + * elf.c (bfd_elf_set_group_contents): Exit on zero size section. + +2019-05-27 Alan Modra + PR 24596 * linker.c (_bfd_generic_link_output_symbols): Heed BSF_KEEP. diff --git a/bfd/elf.c b/bfd/elf.c index 952e4bf..b463f1d 100644 --- a/bfd/elf.c +++ b/bfd/elf.c @@ -3472,7 +3472,8 @@ bfd_elf_set_group_contents (bfd *abfd, asection *sec, void *failedptrarg) /* Ignore linker created group section.
