Building guile-2.2.2 seems fine on Ubuntu 17.04, but fails with

Warning: Unwind-only `out-of-memory' exception; skipping pre-unwind handler.
FAIL: test-out-of-memory
==================================
1 of 39 tests failed
Please report to bug-guile <at> gnu.org

on Ubuntu 17.10.  libgc is the same version on both, but gcc is different...
and if I pick gcc-6 on ubuntu 17.10 (instead of the default gcc-7),
it seems to succeed.

This appears to be fixed now.  After a successful make check with the
debian packaging of 3.0.10[1] on
https://db.debian.org/machines.cgi?host=perotto in a ppc64el chroot, I
ran that tree's test-out-of-memory in a loop for a while with no
crashes.

[1] Still specifies -fstack-protector-strong.
