Hello
I did create a project from a stationery and I am using putchar.
The generated project does not use any function called _put_char or _fwide.
The issue you are facing is probably related to something specific in your environment,
I would recommend you to submit a service request for that.

Make sure to attach a reproducible project and installed product information to the service request.
