[14:28:27] <LebedevRI> hello. is there a gcc bug# for this issue already https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=871250 ? i can only find https://gcc.gnu.org/bugzilla/show_bug.cgi?id=78019 but that is different
[15:15:17] <redi> LebedevRI: I don't recall seeing one.
[15:15:26] <redi> " I'm unable to report this upstream, since registration is closed, and password recovery does not seem to function."
[15:15:26] <LebedevRI> now you do :/
...
[15:21:27] <redi> LebedevRI: anyway, if it's a bug in gcc5 and is fixed in gcc6 then there's no point in an upstream bug report
[15:21:35] <redi> it would probably be closed as FIXED
[15:22:19] <LebedevRI> great. can i quote you on that?
[15:22:49] <redi> sure
[15:23:10] <LebedevRI> problem being, i can't just go and bump compiler requirement up to 6
[15:24:03] <LebedevRI> so the fact that gcc5 is the only one with this issue does not help
