[Bug ld/14590] ifunc problem: internal error, aborting at elf64-x86-64.c line 3175 in elf_x86_64_relocate_section
http://sourceware.org/bugzilla/show_bug.cgi?id=14590 --- Comment #1 from Michael Matz 2012-09-17 15:31:45 UTC --- The problem seems to be specific to common symbols. With -fno-common it goes away. The hash slot for the 'index' symbol get type STT_GNU_IFUNC in elf_link_add_object_symbols when reading the libc.a symbol table, even though it's only a weak def, and the slot referred to STT_OBJECT before. We don't get a type-changed warning because type_change_ok is true. I think we shouldn't regard weak defs to override common symbols. But whatever we do, we must not segfault here, and preferrably still generate expected code (as in, all references to index resolving to the common symbol). -- Configure bugmail: http://sourceware.org/bugzilla/userprefs.cgi?tab=email --- 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

This is a problem also with older binutils. This requires a libc which has
the symbol 'index' defined as weak ifunc:
18: 41 IFUNC WEAK DEFAULT1 index
It only happens when linking statically. The abort is this one:
3170 bfd_vma plt_index;
3171 const char *name;
3172
3173 if ((input_section->flags & SEC_ALLOC) == 0
3174 || h->plt.offset == (bfd_vma) -1)
3175abort ();
The reference this is about is from .debug_info (i.e. !SEC_ALLOC), hence
the abort. I don't know why it things it finds the ifunc definition
first (h->type is STT_GNU_IFUNC here), not the one in the COMMON section.
