Again, you are not giving us accurate information. (Maybe because your tools are lying to you.)

When I run the above program, I get this output:

And when I run that regex against a million word string, it runs perfectly.

At this point, I can only reiterate my earlier advises:

1. Stop running your code inside Komodo -- it appears to be lying to you.
2. Post real code and a small dataset that reproduces the problem -- outside of Komodo -- and you stand a chance of getting a solution.

Until then, I'm diagnosing this as a Komodo problem, which I cannot help you with, and which is beyond the scope of this forum.
