--- Comment #17 from ncahill_alt at yahoo dot com --- This was the only test that failed for me, the others were debug info in LTO mode. I'm very glad that GCC 6.1.0 works so well and built cleanly like it did. This test was a minor thing because I don't use -O3 at all. I just thought, since it was the only test to fail, it seemed worthwhile mentioning it so that the testsuite would be very clean indeed. Thanks, hopefully I've given enough info for the fix to be obvious. Neil Cahill
