Without the corefile, we know nothing, sadly. The binaries are PIE and
we need to know not only where they were mapped but also where glibc was
mapped, how the stack(s) looked like and much more context.

OTOH, it looks like the corefile may be enough very soon, if our planned
magic actually works. I'll know hopefully at the end of this week.

With that, We're now going to thoroughly check the BFD restart because
that's the most likely suspect.

Thanks for your reports!
