I've run the following script on an IBM RS-6000 running AIX 3.2.5, an SGI
Iris 4D35 running IRIX 5.3, and a Sun SPARC 20, running Solaris 2.4.

for (1..1000000) { }

On all three machines the process takes up all the memory/swap space
available and then dies.

I'm running perl 5.001m on all three computers.

Here's the result of the myconfig command on the IBM:
