--- Comment #8 from Segher Boessenkool <segher at gcc dot gnu.org> --- Can we have a testcase please? It sounds like the glibc you used was misconfigured. Of course VSX registers are not restored by the GCC unwinder stuff if you configured GCC to not support VSX registers at all! Typically you should configure for --with-cpu=power7 or later.
