PCRE2 — Perl-compatible regular expressions (revised API)
This function makes a copy of the memory used for a
compiled pattern, excluding any memory used by the JIT
compiler. Without a subsequent call to
pcre2_jit_compile(), the copy can be used
only for non-JIT matching. The yield of the function is NULL

sufficient memory cannot be obtained.
