I'm trying to use the addr2line source as an example of using bfd to map the
addresses from the glibc backtrace() back to file and line number. In the
process I realized that addr2line doesn't report the correct address.
This seems like a bug.
gdb reports:
(gdb) bt
#0 0xe410 in __kernel_vsy
--cref was broken by --as-needed. cref stores the string pointer from
a dso. When memory of unused dso is freed, cref reference is corrupted.
