So downloading the package and testing that with problematic 6.3 does not
reproduce. Can you please verify you have really GCC 6.4? If so, would it be
possible to create a virtual machine or a Docker image which I can replay and
thus reproduce?

gparted build log

Here's the build log from my Gentoo colleague.

If you need more, please tell me precisely what - I dont have that much
experience reporting here yet. Can't reopen the bug either.

Please provide one more test-case that still fails and I will take a look. Feel
free to reopen it.

Fixed on GCC 6.x, no plan to backport back to GCC 5, closing as resolved.

Uh, sorry. I mean when compiling my own application against glibmm and gtkmm,
using LTO on my app (only).

I get similar issues when compiling glibmm-2.4 from git with g++ 6.3 and LTO,
but not without LTO: undefined references to destructors for
Glib::RefPtr and Glib::RefPtr.

Can this be related, or should I open another bug?
