LABEL_REGION on large array --> segmentation fault, please HELP !! [message #85807]

Dear all,

I have a very large binary array with around [60000 by 90000] elements whose file size is about 5GB. I hope to apply LABEL_REGION function on this array to extract "connected" patches. My IDL code was run on a linux machine with 64GB memory. But IDL kept crashing when running through LABEL_REGION function, ending up with error message of "segmentation fault". I'm wondering if IDL has any limitation the size of array that a function can handle? Or this crashing is caused by configuration of my machine? Any idea how to this problem will be appreciated!!
