/usr/lib64/samba/libsamba-debug-samba4.so is linked with BIND_NOW and references gettimeofday, which has an IFUNC resolver on ppc64. However, on Red Hat Enterprise Linux 6, glibc processes relocations in the wrong order, so when the IFUNC resolver runs, libc.so.6 has not yet been relocated. As a result, there is a crash during relocation. See bug 1398716 for details.
We cannot change the dynamic linker behavior at this point in the Red Hat Enterprise Linux 6 product life-cycle, so the only way to fix this issue is to recompile samba4 without BIND_NOW.
