Research direction
The report names sscanf, a %d conversion, and a uint16 variable, with an attached screenshot but no source file or test. Start by reproducing the described call and tracing the C library implementation used by RT-Thread; completion requires clarifying the intended behavior and verifying it with a focused regression test.
