You are trying to make an array that requires

IDL> print, 5287*7707*8*4
1303901088

about 1.3 GB.

This is doable on a 32-bit system (assuming that you have 2 GB of RAM),
but you will not be able to create two such arrays.

Try

HELP, /MEM

to see how much memory you are using before you try to create the array.
