Well, grsecurity made their patches proprietary in 2017. Subsequently, Gentoo has dropped PaX support from the Emacs package, as well as "hardened" Linux sources. So, I no longer have access to an environment where I could reproduce this bug. The following posting pretty much summarises the Gentoo point of view: https://archives.gentoo.org/gentoo-dev/message/0283ed6004111127e0e575cc912feff1 I'd suggest to close this bug. If there are similar problems with the portable dumper, it may be cleaner to open a fresh bug for them.
