If not, is it possible to record the instructions and reverse the inferior? When I recorded fclose(), I got the following message. The next instruction is syscall munmap. It will free the memory addr = 0xb7fe0000 len = 4096. It will make record target get error. Do you want to stop the program?([y] or n) Thanks in advance. -- Best Regards, Sean Chen
