I can't reproduce in my current version. I'll close the ticket as it's likely fixed by other changes. ** Please retry with Devel-NYTProf-2.10_93.tar.gz (or later) as soon as possible ** If you can reproduce it then reply to this and include your perl -V output. Thanks.

I'm guessing your perl version is <5.009005 Please include your "perl -V" output. I've taken a guess about the likely cause and included a fix in Devel-NYTProf-2.10_95.tar.gz - which I've just uploaded to CPAN. Please try it out.
Please retry with r905 (or Devel-NYTProf-2.10_99.tar.gz which I've just uploaded to CPAN)

Closing. (Please don't reply, unless there's a problem, as that reopens the ticket :)
