Hehe, as I suspected. Something with the allocator. Could you check this call successful on your machine (some printf is enough, mem.base() and mem.size() is important):

311    inline PassRefPtr<ExecutablePool> ExecutablePool::create(size_t n)
312        {
313            Allocation mem = systemAlloc(roundUpAllocationSize(n, JIT_ALLOCATOR_PAGE_SIZE));
314            if (!mem)
315                return 0;
316            return adoptRef(new ExecutablePool(mem));
317        }

CC'ing Gavin, he is the allocator expert.
