Programs still segfault. :-(
And just adding on that, it doesn't look like an issue of using the correct flags or not. GNUstep-base works fine for me on a Debian system with Testing, i.e., the upcoming version 11, installed. But there the binutils package is at version 2.34 already. On the other hand, on Debian 10, where I get segfaults when using bfd for the linker, binutils is at 2.31. So it seems likely there was bug in binutils that got fixed somewhere in between those releases. Wolfgang
