All the tests I could do with the new engine pass. However, it is
noticeable slower than the old engine. If this bothers you, set the
'regexpengine' option to one.
If you spot a mistake in regexp pattern matching, please send a
reproducible example, so that we can add it to the tests.

The above is with "tiny" features but "huge" features give me the same
(with a much longer gcc command line).
Trying to run the resulting executable (previously it worked with no
problems):
