The problem is that if I let the program use 6-7 GB out of my total

that the machine is not swapping when these crashes occur.
Now, I would be willing to blame this on bad memory, but the machine
runs weeks on end performing other heavy computational tasks
(although in 32-bit mode). The same problem also occurs on a separate
dual G5 with 8 GB of memory.

Your RAM is incompatible with your machine, or you have a bad RAM
DIMM. Run the Apple Hardware Test which came with the machine. In
32-bit mode, your application can only access 4GB of RAM. In 64-bit
mode, it's accessing previously unused RAM; accessing that RAM is
causing the machine check panic.
