> $ cat tst-debug1.out
> Didn't expect signal from child: got `Bus error'

That is probably a real bug that needs a backtrace extracted. Needs more debugging.

> $ cat tst-ldconfig-ld_so_conf-update.out
> error: tst-ldconfig-ld_so_conf-update.c:112: not true: dlopen (DSO, RTLD_NOW | RTLD_GLOBAL) != NULL
> error: 1 test failures
> running post-clean rsyn

I vaguely remember seeing in on amd64 as well. Unclear why it happens. Needs more debugging.

Probably a test dependent on specific locale presence (glibc usually generates needed ones automatically though). Needs more debugging.

Same as previous.

This one is mysterious. Is it deterministic?

Looks like it. Like the other tests it fails on my Talos' ppc32 chroot too. Also fails on ppc64 (bug #751967).
