+// Issue 4396. Arrays of bytes are not required to be
+// word aligned. 5g should use MOVB to load the address
+// of s.g[0] for its nil check.
+//
+// This test _may_ fail on arm, but requires the host to
+// trap unaligned loads. This is generally done with
+//
+// echo "4" > /proc/cpu/alignment
