Mention any other details that might be useful.
This error is still occurring in 1.3.0-rc.5, the regression was added in 1.2.2, 19f04af.
If a runtime errors occur during the constructor then the proper error displays, but sourcemaps still fail to show line in TypeScript.
It would be best if the actual error and line in typescript could be referenced.
