VS 2013, Python 2.7
Here are 2 examples of exceptions I've seen when remote debugging on localhost.
It's the guess a number sample, with a enable_attach and wait_for_attach at the beginning. Attach unsecured and run through the end of the program. Doesn't matter if there are breakpoints or not.
I've seen this error once:
Unhandled exception in thread started by <bound method DebuggerLoop.loop of <ptv
sd.visualstudio_py_debugger.DebuggerLoop object at 0x02219C10>>Press any key to
continue . . .
I've seen this one multiple times:
Unhandled exception in thread started by
sys.excepthook is missing
Press any key to continue . . .
