Wrong coverage with function named `error`

I have to investigate more on what exactly can cause this, but here is the coverage of one of my [files](https://github.com/yanickrochon/co-efficient/blob/master/lib/parser.js) :




I had to add the `console.log` to see if these lines were actually being executed or not...

Especially when the function is actually being called and properly covered.


The issue is about incorrect coverage reporting for a function named 'error' in lib/parser.js. Start by examining the coverage tool's instrumentation and reporting logic, likely in the main semcov source files. Reproduce the issue by writing a test that calls the 'error' function and check the coverage output. Look at how function names are tracked and why 'error' might be misreported.
