Incorrect Line numbers for script errors

Link to bug demonstration repository

Expected Behavior

Running the command
../node_modules/.bin/nyc --cache false --source-map ../node_modules/.bin/mocha Test/Spork.js
Should produce coverage with correct file and error line numbers

note attempted to use inline and linked source maps

Observed Behavior

Running the command

../node_modules/.bin/nyc ../node_modules/.bin/mocha Test/Spork.js
Produces no coverage if source map urls are present in tested files

If no source map urls are present in tested files
../node_modules/.bin/nyc ../node_modules/.bin/mocha Test/Spork.js
then coverage is as expected but error lines are incorrect

If running the command
../node_modules/.bin/nyc --source-map ../node_modules/.bin/mocha Test/Spork.js
then no coverage is produced and line numbers are still incorrect

Running the command
../node_modules/.bin/mocha Test/Spork.js
produces the expected results showing the correct file and line number for the error

Troubleshooting steps

• still occurring when I put cache: false in my nyc config
