RE: Pointer Question

[Jim Langston <jlangston@xxxxxxxxxxx>]

I seem to recall that reallocing may change the address the memory points to
(in C anyway) but it's a vague memory.  I think you'll want to re-set the
pointer to that address that remalloc returns every time.

Although I could be wrong.

I thought I was wrong once, but I was mistaken.

I've got a MODS based on a pointer with OCCURS = 32767.  I ALLOC & REALLOC
memory to the pointer all during the program.  At some point, I DEALLOC the
pointer and it changes to a NULL pointer.  If I then ALLOC to it again, the
pointer takes on a valid address, but references to the MODS cause a space
offset error (MCH0601) due to trying to operate outside of  "an implicit
process space for activation group-based heap storage".

Is there a rule about not being able to reallocate memory to a pointer once
it has been deallocated or am I just doing it wrong?  The pointer itself
looks like a valid address, but apparently the MODS is no longer based on
it.
