The current strategy for host allocation is to choose a random address and attempt to allocate there, eventually failing if the allocation cannot be satisfied. The C standard only guarantees that RAND_MAX >= 32767, so for platforms that use a very small RAND_MAX allocations will fail with very high probability. On such platforms (Windows is one), you can reproduce this trivially by running lldb, typing "expr (3)" and then hitting enter you see a failure. Failures generally happen with a frequency of about 1 failure every 5 evaluations. There is no good reason that allocations need to look like "real" pointers, so this patch changes the allocation scheme to simply jump straight to the end and grab a free chunk of memory.
