Er, how long is the string you're matching against?  It really helps
if you include the exact input you're using so that others can
reproduce your problem.  I shouldn't have to spend my time constructing
arbitrarily large inputs with different permutations of strings (e.g.,
containing Baseline, not containing it, containing thousands of characters
before a newline, not, etc.).  Which, by the way, I just did.

When you don't need capturing parentheses, don't use them.  In
other words:
   Baseline(?:.)*
And when you don't need grouping, don't use it.  In other words:
   Baseline.*

As I said before, Perl regular expressions are miniature programs ...
