possible bug #720

Closed ORESoftware closed 7 years ago

ORESoftware commented 7 years ago

This is a weird one, been trying to debug it for awhile, used the new node --inspect feature. I put a debugger; statement at the very very top of my file (the entry point file), and I can't reach that debugger statement, so seems to happen in the Istanbul instrumentation code.

This problem is happening for both Node version 6.2.2 and version 7.0.0.

First the error:

 => Uncaught exception => 
 SyntaxError: Unexpected token u in JSON at position 0

it seems to happen in this file:

not sure what's happening, seems like internal error?
