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.ha...@gmail.com
Reporter: cmbecke...@gmx.de
CC: pcre-dev@exim.org
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

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