/* Handling large aligned variables.
   Large aligned variables take a different code-path through expand_stack_vars
   in cfgexpand.c.  This testcase is just to exercise that code-path.

   The alternate code-path produces a second base-pointer through some
   instructions emitted in the prologue.
   
   Test cases are:
   0) Valid access works without complaint.
   1) Invalid access is caught.  */
