I am definitely for the "Right Aligned" one and against the "Left Aligned"
one.  While analyzing various crash dumps one looks for the same last three
digits (ignoring PIC/PIE different PAGE_SIZE-aligned placement).  Also
sometimes sorting addresses from various sources by hand to find out the
memory layout and having to additionally re-align even the GDB dump itself is
not helpful.
