The linker bug was meanwhile fixed.  Unfortunately I didn't save any of the
broken executables - the referenced bug says libstdc++ tests were broken,
but as far as I remember every executable compiled with -g -flto
-Wl,--gc-sections was broken due to stripped relocations.  It might be poss=
ible
to dig out an old BFD ld and create an affected executable that way (plus o=
ld
gdb
to check if the segfault was reproducible).

Not sure if worth - feel free to close the bug instead.
