I checked and found that the distro (Gentoo) is actually explicitly passing --enable-warn-execstack, so any change to the defaults doesn't help: https://github.com/gentoo/gentoo/blob/master/sys-devel/binutils/binutils-9999.ebuild#L251 I tested at that commit and when --enable-warn-execstack is passed, the issue is still present. What I don't understand is why toggling this warning on or off changes the behavior of the linker - shouldn't it just be a purely informational warning? -- You are receiving this mail because: You are on the CC list for the bug.
