Thanks to you Gianfranco, we now know that the issue is not at gcc level.

I think so ... if you configure gnustep-make with specific values in the CCa and CPP environment variables, those values should be used for the compiler when building gnustep software.

Eric, if you want a test build on a porterbox I can do it, just give me a list of commands to issue and I'll happily execute them for you (please note: porterboxes don't allow "everything", so debugging might not be trivial to perform) G.

Thanks Gianfranco, There just two tests to do: * build gnustep-make with gcc-6 I think a CC var should be set when calling configure script (Richard ?) in debian/rules. * replace libffi-dev build-dependency by libffcall1-dev. (and trying to build with ggc-5 and gcc-6) Eric

You can ask for an access to Debian Porter machine: https://db.debian.org/machines.cgi https://dsa.debian.org/doc/schroot/ But I am afraid that the hard part is to isolate the compiler issue: for me, it was solve somewhere between gcc-5 and gcc-6. hth, Jerome

Debug and fix gcc-5 is preferred, otherwise something like add gcc-6 to build dependencies (and g++-6 if needed) export CC=gcc-6 export CXX=g++-6 should do the trick on most sane build systems. G.
