TypeError: Cannot read property 'g' of null #2440

I'm using closure-compiler with rollup, for a babel-transpiled library (https://github.com/helion3/inspire-tree). I'm seeing the following errors, both on node v6 and node v7.9.0.

This stack trace does not include any closure compiler code, so it's hard to know what's going on. Please try to reproduce using the compiler's command line, and provide us with repro steps. Closing issue for now.

Dominator008 commented 7 years ago

Looks like you are using rollup-closure-compiler-js. The stack trace is from the GWT-compiled version of Closure Compiler. Could you give me a clear step-by-step guide to reproduce the problem? Thanks.

tadeegan commented 7 years ago

Perhaps it would be good to distribute a pretty printed version of the GWT compile so that the stack trace is somewhat useful.
