Subject: [PATCH] Fix range check in JIT path
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
Jitted range check was wrong:
re> /[efij]/S+
data> e
No match
while interpretted path is correct:
re> /[efij]/
data> e
0: e
This fix is part of:
commit c07887b22a83fba842e88889c9e57a622b9ee439
Author: zherczeg <zherczeg@2f5784b3-3f2a-0410-8824-cb99058d5e15>

The auto-possessification of character sets were improved. The JIT compiler also optimizes more character set checks.
