The arguments are a starting size for25the stack, and a maximum size to which it is allowed to grow. The result can be26passed to the JIT run-time code by \fBpcre[16|32]_assign_jit_stack()\fP, or that27function can set up a callback for obtaining a stack. A maximum stack size of28512K to 1M should be more than enough for any pattern.
