Control: forwarded -1 PIPE-7104 I forwarded the bug to the ESO bug tracker. The bug tracker is not public; therefore I can't give a complete URL here.
I am however pessimistic about getting this fixed for Stretch: Upstream tends to not care too much about licensing issues, and I couldn't find a way to replace the non-free functions with free equivalents. Help and patches are welcome, however. GSL anyone? Best regards Ole
