Ruslan Ermilov a1b0a18096 Prevent IOC_IN with zero size argument (this is only supported 
if backward copatibility options are present) from attempting
to free memory that wasn't allocated.  This is an old bug, and
previously it would attempt to free a null pointer.  I noticed
this bug when working on the previous revision, but forgot to
fix it.
