As was listed in Changelog to version 8.31:
23. Support PCRE_NO_START_OPTIMIZE in JIT as (*MARK) support requires it.
On the other hand PCRE documentation says in two places of pcreapi.html:
The use of PCRE_NO_START_OPTIMIZE disables JIT execution; when it is set,
matching is always done using interpretively.
The optimizations can be disabled by setting the PCRE_NO_START_OPTIMIZE option
when calling pcre_exec() or pcre_dfa_exec(), but if this is done, JIT execution
is also disabled.
It seems that 8.31 change no23 is not reflected in documentation. Or I don't
understand something?
Thanks.
