I don't know why pointers cannot be used. Can you show the
struct definition you're using?
Our configuration is a struct of several static hash tables
(allocated in-place, not via GC). So the entire configuration is
contiguous is memory, which allows us to dump/load/send it easily.
When we increase the capacity of these tables we run into these
pain-in-the-ass 16MB limits. So although the struct itself is
over 16MB, no single table can cross several thousand entries, as
the static arrays it uses internally would overflow that boundary.
The configuration itself may very well be dynamically allocated
(e.g., not a global variable) but that won't solve anything as
the restriction is on the *type* of the array.
