This means you have passed NULL to a function that doesn't expect it.
You have called pcre2_match() with either code, subject, or match_data
== NULL. (The value is also given by some of the auxiliary functions,
but I'm assuming in a simple demo you are not calling any of them.)
Note: you can get a textual error message by calling
pcre2_get_error_message().
