"Error: original.line and original.column are not numbers" after upgrading to 7.11.5 #12025
Description
Bug Report
Current behavior
Transpiling basic file with --source-maps option crashes as follows
$ babel index.js -o dist/index.js --source-maps
Error: original.line and original.column are not numbers -- you probably meant to omit the original mapping entirely and only map the generated position. If so, pass null for the original mapping instead of an object with empty or null values.
