Increasing PCRE_JIT_STACK_MAX_SIZE[1] to, say, 256 kibibytes should suffice in this case.

Test script: --------------- It is quite lengthy so please see https://3v4l.org/EUu5k - the meat of it is in the last 10 lines, the rest is just a long test string we have in the composer test suite (that's where I found the failure: https://travis-ci.org/composer/composer/jobs/394160719 ) Expected result: ---------------- It should match as expected much like on older PHP releases ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=76514&edit=1
