Re: test-out-of-memory fails in v2.2.2?

[Dan Kegel]

I noticed something funny: on Ubuntu 17.10, the test fails if I build
with gcc7 (the default), but passes if I build with gcc6.

To select gcc6, I did

  sudo update-alternatives --install /usr/bin/gcc gcc /usr/bin/gcc-6 6
--slave /usr/bin/g++ g++ /usr/bin/g++-6
  sudo update-alternatives --install /usr/bin/gcc gcc /usr/bin/gcc-7 7
--slave /usr/bin/g++ g++ /usr/bin/g++-7

and picked gcc-6 with

  sudo update-alternatives --config gcc

That almost seems bug-worthy.  I mentioned it at
https://bugs.launchpad.net/ubuntu/+source/guile-2.2/+bug/1734575
but perhaps I should report it to guile-bugs, too.
