--- Comment #1 from Philip Hazel <ph10@???> ---
Thank you for the report, but the pcre2_match() function has been totally
refactored for the next release (see the head code). Its handling of
backtracking no longer uses recursive function calls, but instead uses the heap
where necessary. I have checked your test, but I'm not sure I got it right,
because the listing of the pattern ":(\S)+\V??" does not contain \x{e3}\x07
which appear in the compiled code. I see the subject line as "?+?". Is that
right? I cannot reproduce your report in 10.23 using clang. Perhaps you could
attach the POC1 file.

For fuzzing tests, please download the latest SVN source code from

svn co svn://vcs.exim.org/pcre2/code/trunk pcre2

It just wastes time when bugs that have already been fixed are re-reported.
Thank you.
