Is this on windows? There was a thread here dealing about memory
fragmentation etc. some time ago, if I remember correctly the
conclusion was that there is not so much one can do in windows,
but a few tricks could help a bit, and that linux manages the
memory better. But anyway with idl 6.0 or less there is no chance
to allocate a very large array because of the "array has too many
elements" limit anyway.

Can you allocate two double (real) array instead of a complex one?

Ciao,
Paolo
