Bug#1023229: f3d: autopkgtest regression on s390x: Compare with ref failed

2022-10-31 Thread François Mazen 
Hello Paul,

thanks for reporting the issue, I've investigated and this is an Assimp
problem that I've reported here:
https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=1023212

The big endian architecture may be the root of the issue, thanks for
pointing that out.

Best Regards,
François

Bug#1023229: f3d: autopkgtest regression on s390x: Compare with ref failed

2022-10-31 Thread Paul Gevers 

Source: f3d
Version: 1.3.1+dfsg-3
Severity: serious
User: debian...@lists.debian.org
Usertags: regression

Dear maintainer(s),

With a recent upload of f3d the autopkgtest of f3d fails in testing when 
that autopkgtest is run with the binary packages of f3d from unstable. 
It passes when run with only packages from testing. In tabular form:


   passfail
f3dfrom testing1.3.1+dfsg-3
all others from testingfrom testing

I copied some of the output at the bottom of this report. I note that 
s390x is our only big endian release architecture (just in case that 
matters to the problem at hand).


Currently this regression is blocking the migration to testing [1]. Can 
you please investigate the situation and fix it?
