The arguments are a starting size for 39 the stack, and a maximum size to which it is allowed to grow. The result can be 40 passed to the JIT run-time code by <b>pcre[16|32]_assign_jit_stack()</b>, or that 41 function can set up a callback for obtaining a stack. A maximum stack size of 42 512K to 1M should be more than enough for any pattern.
