This appears to be an improvement!

Next I'd suspect your regex is causing issues. Try some logging to
figure out what lines are causing issues with the regex expression you
defined (and perhaps incorporate Ulf's suggestion to use binaries).
If you don't find a solution there, it could well be that you'll have to
push the results out to ETS as Ulf suggested (and my experience is that
Ulf is generally right about such things - not to mention the fact that
he has many more years of experience with OTP than I do).
