I cloned this repo: https://github.com/adrianhall/example-typescript-webpack
then npm install and if I make npm run prepublish it generates the js files normally, but if I change the declaration to declaration:true in tsconfig.json then npm run prepublish just hangs, right after it generates the .js files. For now whatever I try the ts-loader doesn't generate the d.ts file for my bundle and always hangs after it generated the js files.

I saw the similar issues were fixed some time ago, like with this pull request: https://github.com/TypeStrong/ts-loader/pull/175, but in spite the version was 0.8.2 it doesn't work for me at all
