Created attachment 643232 [details] build.log Please see the bottom of the attached build log for further details. The problem is that the most recent *stable* version is automake-1.16.1-r1. Thus, stable harfbuzz-2.6.5 depends on unstable automake-1.16.2.

(In reply to Andreas Sturmlechner from comment #1) > Do sync. > > *** This bug has been marked as a duplicate of bug 726674 *** Thanks. I am wondering, exists there a Gentoo machine that builds *all* stable packages when a formerly unstable ebuild is stabilized before it is commited to Gentoo's git repo, like in the case of harfbuzz 2.6.4 -> 2.6.5, and rejects the patch if the upgrade fails to build? It might be quite useful for such machine/machines to exist. With a huge ccache (1 terabyte, SSD drive) and no optimizations (CFLAGS="-O0") the verification process might be sufficiently fast to be usable in practice.
