Invalid source map with rollup 0.40

[tromey]

mozilla/source-map#247 mentions a source map problem with preact. A couple of the generated source maps are definitely wrong -- they refer to lines that don't appear in the generated file. I looked into this and found rollup/rollup#1254. Changing preact to require rollup 0.41 makes the bug go away.

Nice! Feel free to submit a PR that updates Rollup, otherwise I'll make sure that's in the next release.

@developit This still seems to be an issue. I get the mentioned source map issue only when using preact, preventing me from using Webpack source maps in my production build.

@tromey Are you still seeing this issue?

I don't actually use preact; I just found this while investigating a bug filed against the source map library. So, I don't know, sorry!
