! The call to MOVE_ALLOC below caused a seg fault in runtime.
! This was discussed in:
! https://groups.google.com/forum/#!topic/comp.lang.fortran/ZVLqXFYDZ0M
! Richard Maine proposed that the code violated the restrictions on
! actual arguments in F2003 12.4.1.7 and so the fix asserts that the
! TO and FROM arguments cannot be the same object or subobjects thereof.
