JFYI - this might affect us, too, at least for debugging or testing.

If there was an announcement anywhere else, I missed it. I read this just by
accident on [opensuse]:

LD_PRELOAD does not work for setuid applications - and that's the
correct behaviour for quite some time...

And it is of course incorrect.

$ ./xx
$ LD_PRELOAD=/suse/meissner/ ./xx
$ su
# LD_PRELOAD=/suse/meissner/ ./xx

Still looking fine.

Please make xx setuid root and run again as user,
