TypeError: 'caller', 'callee', and 'arguments' properties may not be accessed on strict mode functions or the arguments objects for calls to them

I decided to enable debug mode for my connection pool to identify any potential issues. For some reason I am getting spammed with the following error:

TypeError: 'caller', 'callee', and 'arguments' properties may not be accessed on strict mode functions or the arguments objects for calls to them

Any ideas why I am getting this?

Start at lib/connection.js:471 and trace the addCommand call from lib/connection.js:114 through lib/pool_connection.js:7, lib/pool.js:54 and lib/pool.js:167. Compare this path with promise.js:337-338 and reproduce the debug-mode pool call described in the report; done means explaining the strict-mode TypeError and preventing the repeated error without breaking pool execution.
