Note that this issue is more likely related to exceeding 32-bit counter space (or 31-bit when using signed numbers) than exhausting the virtual memory of your system.

R3-Alpha was retrofitted to be able to build as 64-bit, e.g. the binaries could run on 64-bit systems without a 32-bit subsystem to enable it. These changes were formalized over time in Ren-C to respect alignments better.

Yet there are still places in the code that use 32-bit numbers and assume you won't exceed that. This requires review on what the policy is going to be for the system w.r.t. what should be allowed to crash the system and what should be trappable errors. Similar questions exist for a formal policy on stack overflows--which is more pressing.
