Compling code that uses macro with the rangepos option produces errors like this:

scala.tools.nsc.interactive.RangePositions$ValidateException: Synthetic tree [251] contains nonsynthetic tree [250]

Ran into this in the context of mixing scoverage with a library I'm maintaining (see wix-incubator/accord#60). It is indeed a non-issue for 2.11, but it basically breaks 2.10 if you use -Yrangepos for any reason, such as getting code coverage.
