HEADSUP! With PCRE 8.39 the JIT related code was changed in the way, that additional valgrind options became almost unavoidable. Valgrind had it already sometimes hard with JIT, now there are seem to be more cases requiring special valgrind options. For this reason, the new configure option --with-pcre-valgrind was introduced. The option is development/debugging only and turns on the Valgrind related pieces in PCRE, so then false positives are avoided to the big part. In addition, run-tests.php was added a new valgrind option, when the leak check is enabled and the test filepath contains pcre. Thus, to debug the code related to PCRE with JIT enabled, two things would likely make sense - configure --with-pcre-valgrind - valgrind option --smc-check=all if run-tests.php is not used The checks so far reveal no new issues.
