Thank you for your guide,

I managed to create a self contained example that reproduces the problem.

Now, I ran your test and it works on both perl versions, as you said.

But running the regex inside Expect.pm fails.

So the bug is in the expect package?

  • Are you posting in the right place? Check out Where do I post X? to know for sure.
  • Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:

  • Snippets of code should be wrapped in <code> tags not <pre> tags. In fact, <pre> tags should generally be avoided. If they must be used, extreme care should be taken to ensure that their contents do not have long lines (<70 chars), in order to prevent horizontal scrolling (and possible janitor intervention).
