Description: We are encountering a critical issue in our microcontroller project. We are utilizing ESP-IDF and have found that versions 4.4.4 and older operate seamlessly, however, upon upgrading to version 4.4.5 or later, we face a problem causing the program to halt and subsequently reboot after several seconds. The attached log file delineates the firmware initiation and the point at which it halts. This issue is exclusive to scenarios where we attempt to create an instance of any class in our code and invoke any method of that object (e.g., cout “Hello world”). However, when we transpose the content of the aforementioned class method directly into main, it operates correctly. Key Symptoms of the Issue: The program halts with ESP-IDF version 4.4.5 or newer.
