This is to support issue #741 . For leak suppressions where we don't have good symbols, as in issue #18 , it can help make the suppression more precise without resorting to something brittle like mod+offs.
The size= qualifier is fairly obvious in its simplest form. We could support a syntax for alternate sizes, such as size=18|24|32, and perhaps ranges (size=32<=x<=48)?.
The offset qualifier is useful for possible leaks where we have something like an SLIST_ENTRY embedded in a struct, as occurred in issue #18 ole32!EventEntry::CreatePoolEntry.
