            Bug ID: 2644
           Summary: Erroneous whitespace match with JIT only
           Product: PCRE
           Version: N/A
          Hardware: x86-64
                OS: Linux
            Status: NEW
          Severity: bug
          Priority: medium
         Component: Code
          Assignee: Philip.Hazel@???
          Reporter: cmbecker69@???

I'm forwarding this from <https://bugs.php.net/80118>, because it appears to be
a PCRE2 issue.

Consider the following pattern:

[^\p{Han}\p{Z}]

This is supposed to match a character, which is not Hangul and not a separator.
However, when a space character is given as subject, in JIT mode this is
matched.

cmb@ELEPHPANT:~/pcre2-10.34$ LD_LIBRARY_PATH=/home/cmb/pcre2-10.34/
bin/pcre2test
PCRE2 version 10.34 2019-11-21
re> /[^\p{Hangul}\p{Z}]/
data> \040
No match

cmb@ELEPHPANT:~/pcre2-10.34$ LD_LIBRARY_PATH=/home/cmb/pcre2-10.34/
bin/pcre2test -jit
PCRE2 version 10.34 2019-11-21
re> /[^\p{Hangul}\p{Z}]/
data> \040
0:

This also happens with the current tip of the trunk, but works as expected with
PCRE2 10.32 (I have not tested 10.33).
