There is one condition can lead to program overflow, thus argc==2 and argv[1] has only one character, for example ./tail x , will access the next character after x, this maybe a bug
I don't see a bug there. The next character is a null byte, and ISDIGIT ('\0') is false so the code should do the right thing. I don't think there is a test case that illustrates wrong behavior, but if I'm wrong please reply with a test case (a shell command invoking 'tail') and I'll reopen the bug report.
