Could you post a reproduction?

"I'm not exactly sure, but the issue may arise from frequent entry and exit of the simulator, and the addresses of entry and exit locations are the same."

"In every 'uc_emu_start' call to enter the emulator, executing 'uc_ctl_flush_tb' resolves the issue. Please check. I'm using a complex sample, so reproducing the problem may not be possible."
