wayland and LTO don't seem to fit well together. /tmp/portage/dev-libs/wayland-1.13.0/temp/cc4uzCHx.lto.o /tmp/portage/dev-libs/wayland-1.13.0/work/wayland-1.13.0/tests/test-runner.c:124: error: undefined reference to '__start_test_section' /tmp/portage/dev-libs/wayland-1.13.0/work/wayland-1.13.0/tests/test-runner.c:124: error: undefined reference to '__stop_test_section' /tmp/portage/dev-libs/wayland-1.13.0/work/wayland-1.13.0/tests/test-runner.c:389: error: undefined reference to '__start_test_section' /tmp/portage/dev-libs/wayland-1.13.0/work/wayland-1.13.0/tests/test-runner.c:389: error: undefined reference to '__stop_test_section' /tmp/portage/dev-libs/wayland-1.13.0/work/wayland-1.13.0/tests/test-runner.c:389: error: undefined reference to '__stop_test_section' /tmp/portage/dev-libs/wayland-1.13.0/work/wayland-1.13.0/tests/test-runner.c:442: error: undefined reference to '__stop_test_section' /tmp/portage/dev-libs/wayland-1.13.0/work/wayland-1.13.0/tests/test-runner.c:442: error: undefined reference to '__start_test_section' /tmp/portage/dev-libs/wayland-1.13.0/work/wayland-1.13.0/tests/test-runner.c:107: error: undefined reference to '__start_test_section' ..... collect2: error: ld returned 1 exit status Reproducible: Always

Using the patch from https://bugs.freedesktop.org/show_bug.cgi?id=94602#c2 fixes the issue.
Created attachment 472072 [details, diff] fixlto.patch fixlto.patch for =dev-libs/wayland-1.1{2,3}.0. Works *without* -ffat-lto-objects too.
Marking as fixed should be done when the bug is fixed in the portage tree.
This problem solution was published in https://bugs.freedesktop.org/show_bug.cgi?id=94602 12.4. (almost 2 month ago) and this is still not in portage... :-((
Any news on this?
I can confirm this for dev-libs/wayland-1.14.0, too. Using sys-devel/gcc-7.3.0-r1 and -flto I get the same errors, with the patch from comment 4 the build succeeds.

I suspect that the patch doesn't meet the required standards to be in portage tree. I will fork wayland and make the changes there to get a patch and/or a pull request. The patch will have description, dates etc.
As one can see here[1] the "used" is already added upstream. But for some reason the patch is applied which means that dowstream wayland != upstream. In this case I don't have something to commit and/or create a proper patch. [1]https://github.com/wayland-project/wayland/blob/master/tests/test-runner.h#L42
It's because the patch (https://github.com/wayland-project/wayland/commit/4c920f0f5e591b066544cfda5a2b223ef46334a0) has been applied to master after 1.14.0 was released and is therefor not included in 1.14.0 but in 1.15.0 (officially released on April 9, 2018) which is not in the tree at the moment. You could open a new bug with a version bump request.

You could open a new bug with a version bump request. Thanks. This report can be a dirty workaround for some users. In the meanwhile I will work on testing the 1.15 ebuild after removing this patch from /etc/portage/patches directory.
A patch has gone upstream to fix this in 1.15.0.
