Regression introduced in commit d6623003 (v0.8.8) - using the
wrong sizeof operand meant that security manager private data

supposed to be prevented by the solution to CVE-2010-2238.

I suppose I could have used:
return mgr + 1;
instead, since that gives the same address with less typing. Any
preferences on which form to commit?
