[Debian GNUstep maintainers] Bug#918366: FTBFS for armhf on arm64, fails some tests

[Steve McIntyre]

Package: src:gnustep-base
Version: 1.25.1-4
Severity: important

Hi!

I've been doing a full rebuild of the Debian archive, building all
source packages targeting armel and armhf using arm64 hardware. We are
planning in future to move all of our 32-bit armel/armhf builds to
using arm64 machines, so this rebuild is to identify packages that
might have problems with this configuration.

I've tried to build gnustep-base for armhf on top of arm64, and AFAICS
it's failing some of its tests:

...

I'm honestly not sure about what casues the failures. Is a "dashed
hope" a test fail? :-(
