The default limit for the Prolog stacks is 128 MB on 32-bit and 256 MB on 64-bit hardware. The 128 MB limit on 32-bit systems is the highest possible value and the command line options can thus only be used to lower the limit. On 64-bit systems, the limit can both be reduced and enlarged. See section 2.20. Below are two examples, the first reducing the local stack limit to catch unbounded recursion quickly and the second using a big (32 GB) global limit, which is only possible on 64-bit hardware. Note that setting the limit using the command line only sets a soft limit. Stack parameters can be changed (both reduced and enlarged) at any time using the predicate set_prolog_stack/2.
