memory access benchmark

[cnrdean at ucbtopaz.BERKELEY.EDU]

I am looking for a benchmark program which will test for the 
maximum main memory size that a program can have in a computer.
That is, maybe a computer manufacturer says that a program can be 
64K of data and 64K of instructions.  But, I would like to test to 
make sure that this is true.  

My guess is that to test the data size, I would simply keep 'alloc'ing
until a failure happens.  I would like, not only to declare a
large array, but to test that values are accurately stored.

But, I am not sure how to write a program which keeps incrementing
its instruction size.  Is this possible?

Any help would be appreciated.  If you can send some source, so much 
the better.
