WARN: Couldn't figure out mapping for ?:3,234 - 1,327 []

Basically using the latest version throws a ton of these warnings, I haven't been able to zero in on exactly why its having difficult with sourcemaps. I am using browserify, babelify and rollupify as well and uglifyify was the last in the sequence of transforms, in practice it does seem to locate the sourcemaps correctly (so far), but its really outputting thousands of warnings.

Same here. Is there a way to pass warnings: false to UglifyJS? /cc @hughsk
