--- Comment #1 from Guillermo E. Martinez <guillermo.e.martinez at oracle dot

Hello,
This is happening because cache_bread_1 it's reading less bytes than expected
(3314/6144 in .xt.insn for "property xtensa section")
bfd/cache.c:cache_bread_1: 0xcf2 ()
So _bfd_generic_get_section_contents is returning *false* and propagated to
bfd_get_section_contents, bfd_get_full_section_contents,
bfd_malloc_and_get_section and finally retrieve_contents.
After that, *table_data* variable is not taking care of the return value for
retrieve_contents assuming valid bytes for such section, further used in
bfd_get_32:
bfd_vma address = bfd_get_32 (abfd, table_data + off);
I thinks that it could be fixed as follow:
diff --git a/bfd/elf32-xtensa.c b/bfd/elf32-xtensa.c
index e5bfbb2f509..98039757c22 100644
--- a/bfd/elf32-xtensa.c
+++ b/bfd/elf32-xtensa.c

num_records = table_size / table_entry_size;

Please let me know your comments,
Kind regards,
