Even more simple test causes ld to crash in BFD:
$ g++ -shared -Wl,--as-needed -Wl,--whole-archive `gcc
-print-file-name=libsupc++.a` -Wl,--no-whole-archive
collect2: ld terminated with signal 11 [Segmentation fault]
/usr/bin/ld: BFD 2.16.91.0.6 20060212 assertion fail elflink.c:2317
/usr/bin/ld: BFD 2.16.91.0.6 20060212 assertion fail elflink.c:2318
