Hello, I am wondering if the problem is not a gcc bug.
I tryed to deal with this issue, with the ccan upstream. https://github.com/rustyrussell/ccan/issues/65 but I do not have the skills in order to fix it otherwise than applying the simple one line fix Here the patch I am applying i order to fix the build issue. But it seems that it is not sufficient... https://salsa.debian.org/science-team/hkl/blob/master/debian/patches/0001-889878-make-test-for-pointer-safe-makecontext-succee.patch Cheers Fred
