Subject: Handle the case when SourceMapConsumer.originalPositionFor returns null source.
X-Git-Url: https://git.ndcode.org/public/gitweb.cgi?a=commitdiff_plain;h=014f655c5f9f0a32994ee556e40acbe8349943fe;p=UglifyJS.git

Handle the case when SourceMapConsumer.originalPositionFor returns null source.

This happens when SourceMapConsumer does not have a valid position to map the input line and column. This is a change in mozilla/source-map starting from version 0.1.33

Fixes #436
