Log:
Fix extern3 to account for useful malloc-wrapper analysis' effects.

This test was failing because the addition of the malloc-wrapper
saw through the functionality of these simpler wrappers.

Since this is only meant to test that I/E flags are set appropriately,
  add some store's to the malloc'd memory to ensure the functions are
  not identified as malloc wrappers.
