If you still have the core dump and
/usr/libdata/debug/usr/lib/ld.elf_so.debug, that should be enough to
get a stack trace.  (If all you have is the core dump, you can just
rebuild ld.elf_so from the same source date as before and the
ld.elf_so.debug should work.)

No, haven't tried yet, sorry, was hoping the stack trace was still
available.  Working on fixing several things at once here, not just
ld.elf_so!
