Looking more closely at this change, I can see that your change is
actually showing a latent bug (the code is dereferencing deallocated
memory):

(gdb) p e->flags
$2 = -1347440721
(gdb) p/x -1347440721
$3 = 0xafafafaf

Of course that makes this latent bug more apparent (and even makes it
a regression...)

BTW, don't you need to update the comment in your change:

<<
   /* Now align the size to a multiple of 4.  */
-  size = align_four (size);
+  size = align_eight (size);
>>

The size is now aligned to a multiple of 8, not 4, right ?
