[tex-live] (fwd) Bug#672742: /usr/bin/xetex: xetex fails to compile documents with defaultfontfeatures set

[Norbert Preining]

Hi Arthur, hi everyone,

coming back to a thread from 2010:

I think there is something we have to fix in one of the packages!

This problem was *not* present in TL2009.

Here another instance and analysis sent my a bug reported on Debian.
