25 This function is used to create a stack for use by the code compiled by the JIT
26 optimization of \fBpcre[16|32]_study()\fP. The arguments are a starting size for
27 the stack, and a maximum size to which it is allowed to grow. The result can be
28 passed to the JIT run-time code by \fBpcre[16|32]_assign_jit_stack()\fP, or that
29 function can set up a callback for obtaining a stack. A maximum stack size of
30 512K to 1M should be more than enough for any pattern. For more details, see
