That bug was carried over with git commit 49c09209d0 "Rearrange PLT reloc output on powerpc". If the refcount for an ifunc local sym plt entry was zero, ppc_elf_size_dynamic_sections would correctly set plt.offset to -1 but leave glink_offset uninitialized. That leads to occasional segfaults (which can be made solid with MALLOC_PERTURB_=1 when using glibc). So, guard the write_glink_stub call with plt.offset != -1. Also, remove the totally ineffective attempt at writing multiple-use glink stubs only once. PR 24355 * elf32-ppc.c (ppc_finish_symbols): Don't call write_glink_stub for local iplt syms with ent->plt.offset == -1. Remove ineffective attempt at writing glink stubs only once. -- 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
