Serial Problems with 0017

I'm reading from a GPS serial data with 57600 baud (HW serial) using a Duemilanove ATmega 328.

With 0016 everything works fine, with 0017 I only get gibberish data.
Works better (not perfect though) with lower speeds but unusable at higher speeds.

I wonder if that has something to do with this change:

  • Improving the accuracy of the baud rate calculations for serial
    communication

Tried on Mac OS X and Windows, same problem on both. Fine with 0016, not working with 0017.

Any ideas?

It probably does have to do with that change. Can you file a bug report here? Google Code Archive - Long-term storage for Google Code Project Hosting.
