There is an infinite family of ways a bad/invalid/malicious/corrupt DSO can
cause the dynamic linker to crash. Any bug of the form "dynamic linker crashes
when fed an invalid DSO" should be considered invalid unless there's a strong
argument to the contrary. The DSO in question was not built with old binutils
or glibc; it was built with nonsensical, nondefault options and symbols that
conflict with symbols in the standard library, which is a very bad form of
undefined behavior.
