Shouldn't "MAXACT" be replaced with "MAXPROV"? Depending on your value of
MAXACT, you could be overflowing you buffer below. This could be the cause
of your crash.

By the way, you are going to have a memory leak here. You don't need the
line:
> lista_conprovincia[i] = (Int16) MemPtrNew(sizeof(Int16));
You are allocating memory, then assigning another value over the top of the
memory address.
Hope that helps,
