The issue is with the ArduinoSTL library and has been already reported at mike-matera/ArduinoSTL#84. A PR mike-matera/ArduinoSTL#94 already exists but it has not been merged yet.

So the current workaround for those who use the CSE_ModbusRTU library is to manually edit the new_handler.cpp file.

This issue will remain open until the issue is fixed at the ArduinoSTL library side.
