Hi, Carlos,

I tried this on several systems (varying archs and distros), but I wasn't
able to reproduce it (with elf/tst-ldconfig-bad-aux-cache)...

... even on Fedora 30 for x86_64, so I'm wondering if there's anything in
your configure options that I should try and mimic (I already tried some
combinations of --enable-profile --enable-addons --enable-multi-arch
--enable-tunables --enable-stack-protector=all, but I only tried that with
the system compiler (gcc (GCC) 9.2.1 20190827 (Red Hat 9.2.1-1)).

I never got this.

Nor this.

But this one, I got, too.
