Ok, could you try the following patch for the specs files? That's be appreciated. I've tested those standalone on the Hurd with a synthetic test file, but not as part of GHC build or similar. > I'm however surprised that dpkg adds -pie on hurd-i386 too: AIUI hurd's > gcc does have pie enabled by default too. Very unfortunately nope, supposedly only architectures for which porters requested it to be enabled, which means we have a mess of arches that do PIE by default and others that do not. :( <https://sources.debian.net/src/gcc-6/6.2.0-13/debian/rules.defs/#L1261> If you request it to be enabled on Hurd (which I think would be way ideal), please let me know and I'll mark it as such in dpkg-dev. :) Thanks, Guillem
