The problem applies to 64-bit programs. I can reproduce it with -m64.

Just found this:
http://www.gnu.org/licenses/gpl-faq.html#IfLibraryIsGPL

Quoting:

So I guess that gives us a definitive answer. We CANNOT use binutils or
elfutils, so libdw and libbfd are out of the question. From the discussed
options, that leaves FreeBSD's Elftoolchain, integrating with addr2line, or our
own DWARF/ELF parser.
