--- Comment #12 from Tony Reix <tony.reix at atos dot net> --- Hi Ian We were working on official 6.2.0 version. We are now moving to trunk of version 7. Since we have a proxy issue with SVN for now due to security rules, we'll use the snapshots till the issue is understood/fixed: gcc-7-20161106.tar.bz2 for now, which contains your change of Nov 5th. We'll then check if the problem is fixed. Thx
