I am writing a CFD code which needs 10, arrays of [101][801] in the main
program.

In one function there is another 5, arrays of [101][801],
the program runs fine on a Spark10 but core dumps ( segmentation fault )
at that point.

When the arrays are defined as floats things seem to work.

I have about 64MB of RAM, and assuming that all functions use the memory
at all times, with 3 functions I would need (3*5+8)*101*801*4=15MB

Hardly a problem right?

I look forward to any pointers.

Regards

Jerome
