I'm not into the details of ELF and object file stacks, but Gentoo Linux
gives me some QA warnings about executable writable sections. A Gentoo
hacker helped me by writing a patch to dmd and the security warnings are
now gone.
See http://d.puremagic.com/issues/show_bug.cgi?id=6387 for details.
I posted here to shed some light on the issue. GNU C closures need an
executable stack, but D doesn't. Would there be any other feature that
require executable stacks? If yes, then an option to disable these
features and make the stacks non-executable would help. And why is it
anyway that each object file has a stack of it's own? I thought stacks
were a per-thread thing?
Best regards,
Marco
