[12:35] <ginggs> xnox: re LP: #1950283 you disabled LTO completely there, but it seems upstreams supports LTO, and it only disabling it for that one test seemed to work https://launchpad.net/~ginggs/+archive/ubuntu/testing/+sourcepub/12880546/+listing-archive-extra
[12:36] <ginggs> and the autopkgtests of the affected packages succeeded
[12:37] <ginggs> i ask because there's a new upstream version of r-base in debian i think we should sync/merge before enabling autosync
[14:20] <xnox> ginggs:  sounds good.
[14:20] <xnox> ginggs:  yeah, it's always nice to do things like that before autosync
[14:24] <ginggs> xnox: well yes :) but the question (which i didn't actually ask) was does disabling LTO for that config test seem sane?  and how to propose that to upstream?
[14:25] <ginggs> it is a bit weird, it only seems to happen with -O2 and LTO
[14:27] <ginggs> -O1 or -O3 with LTO is fine
[14:54] <xnox> ginggs:  that is interesting, it would be nice to isolate the conftest.c itself; outside of all the configury things. And see if we can somehow improve it to work correctly. Cause now it sounds that said conftest is lto buggy and doesn't link/reference things it tries to use.
[14:55] <ginggs> xnox: i'll mail it to you
[14:57] <xnox> ginggs:  or subscribe me to the bug report where you attach it? =)
[16:39] <ginggs> xnox: attached to LP: #1950283 (reduce, reuse, recycle)
