places in code which trigger undefined behavior due to
overlapping memory arguments to certain library calls.

# We force -O0 here because memstomp essentially relies on GCC

# and twarting its optimizer isn't something I have any interest
# in maintaining over time.  So just force -O0 for stupid code
# generation.
