After some testing I've found the regression was introduced in commits f32a6055a5 and e0f31baacc, "build-system/gnu: strip with --strip-unneeded", which replace "--strip-debug" with "--strip-unneeded" for packages that use the GNU build system. It seems this is now stripping a bit too much.
The solution may be as simple as undoing this change in (at least) the "static-package" function (guix/build-system/gnu.scm:211). Alternatively we may need to add a "--keep-symbol" flag in a few places. I'm continuing to investigate. -- Simon South si...@simonsouth.net
