I append "-flto=3Dthin -ffat-lto-objects -fuse-linker-plugin -Wl,--thinlto-jobs=3D8" to CFLAGS/CXXFLAGS and it worked nicely until 13-BE= TA1 (last tested one). Yesterday I updated to 13-BETA3, and same options now cause linker issues. Example for Make 4.3: http://s.verknowsys.com/a1b9805fa9c33b148d5ef8d479f3f47c.png (it also breaks with fat LTO enabled, not only with Thin) It builds fine if I just remove "-flto" option. --=20 You are receiving this mail because: You are the assignee for the bug.=
