[OT] gcc: maximum length of an array?

[P.U.Kruppa]

Hi,

sorry for posting an [OT], but usually people on this list know 
everything :-)

Since I don't know too much about programming I am frequently 
fascinated by simple things like Eratosthenes' sieve.
As you might remember, one has to create a boolean array for 
that. The longer the array the more primes can be found.

With malloc() I can create an array of length 100000000 (10^8)
and the first 5761455 primes are calculated in a few seconds.
So of course I would like to test length 10^9 but here my program 
crashes.

So my questions:
 	- is there some way to create a longer array?
 	- or what are the alternatives?
 	- do you know some kind of fine manual about this?

Regards and thanks for all answers,

Uli.
