Yes, I meant perhaps my (alleged) tests were on 15.9 but I had a chance 
to test today and it actually failed on 15.9 too. Anyway a workaround is 
in place now.

I now also found a workaround for oldoffice (#1497) so currently all 
formats pass on Tahiti again.

Oh, except lotus5-opencl fails or hangs intermittently (does on nvidia 
too), only with -test=0 and only intermittenly. That's #1726 and I 
simply can not find the problem.

On an other note, oldoffice needs GPU-mask (as do rakp and ntlmv2) but I 
have yet to understand how to add it. Claudio managed to figure out 
Sayantan's code without help, that was impressing.
