... this was five months ago and silence since then.  We've lost lots of
packages in testing and I see no progress here.  It seems upstream is not
actually keen on working on this as well.  Meanwhile they stepped forward
with new releases and I simply refreshed the issues for the new version
(which are the same and not solved).

Currently we have bus errors on arm 32 bit architectures and a baseline
violation on power.  If there is no solution at the horizon I'd vote for
excluding these three architectures instead of sit and wait (which is all
I can personally do in this topic).

Could someone give this a try?  I know I could use a porter box to do
so but my time is to limited to do it in a sensible time frame.

Kind regards
