see how you've built efl, and if building it with USE=oldlua makes it work
I can try later, but if MPROTECT is required when not using USE=oldlua maybe should apply that on hardened if that was the case (or on hardened in general) ?
(In reply to Thomas Raschbacher from comment #2) we need to gather data first to figure out when it's needed
still the case for 0.21.7 .. it also still is only needed when opengl instead of software renderer is activated
I wonder if there is any point after removal of hardened sources .. waht do you think? https://www.gentoo.org/news/2017/08/19/hardened-sources-removal.html
no grsec anymore so not needed anymore
