Good point. That particular call to memalign, however, is part of a
series of OMPI memory hook tests. The memory allocated by that
memalign call is promptly freed (opal/mca/memory/ptmalloc2/
opal_ptmalloc2_component.c : line 111). The change is to silence
TotalView's memory alignment error when memory debugging is enabled.

Simple malloc() returns pointers that are at least eight byte aligned

value
of four would be be anyway.

No it didn't. And memalign is obsolete according to the manpage.
posix_memalign is the one to use.
