I think that is a documentation issue. Nothing is set in the match data
if an error is detected early. These include:
PCRE2_ERROR_BADOPTION
PCRE2_ERROR_NULL this includes match_data == NULL !
PCRE2_ERROR_BADOFFSET
PCRE2_ERROR_BADMODE
PCRE2_ERROR_BADUTFOFFSET
PCRE2_ERROR_NOMEMORY
and all the errors for invalid UTF strings. In fact, unless the return
code is >= 0 (and possibly for partial matches - I'll look into that),
the contents of the match data are undefined, and the substring
extraction functions must not be called. This should be more clearly
documented, and I will try to do that.
