Turn off highlighting, instruments on sbt-scoverage page.

I can't even work out which line is causing the problem

[sksamuel]

It's a bug in the compiler that was fixed in 2.11.2. It might make it into 2.10.5. But because rangepos was an experimental feature used only by me basically it was never a priority.

@sksamuel Updating to Scala 2.10.5 actually solved the problem. Thanks!

I face the same problem (i think) in my project after adding CsvParser from Parboiled2. I use scala 2.10.6

Disabling highlighting solved the problem

[ryan-williams]

I'm seeing a similar issue with Scala 2.10.6: https://travis-ci.org/hammerlab/guacamole/jobs/180971174

coverageHighlighting := false in my build.sbt also seems to fix it.

Trying to wrap the offending code in:

// $COVERAGE-OFF$
…
// $COVERAGE-ON$

did not seem to work.

[ryan-williams]

@gslowikowski followed up offline; one note from him:

I found the problem. It's not related to Scoverage, but to "-Yrangepos" option. Just add "-Yrangepos" to scalacOptions (scalacOptions += "-Yrangepos") and run "sbt ++2.10.6 compile" (without turning on Scoverage). You will have the same exception.

Since Scoverage is not the root of the problem, you have to turn off Scoverage highlighting option, at least for Scala 2.10.

I've filed SI-10095 about this.

I am also seeing the issue now in a different project, cf. this build. It seems related to my use of Spire in both of the issues in question.
