AFAIK: - only if the compiled binary contains the main function (the kernel doesn't) - only if you use a specific compiler option, which I don't use here To circumvent this I suggest to read http://groups.google.com/groups?dq=&hl=en&lr=&ie=UTF-8&oe=UTF-8&group=comp.arch&selm=a13e403a.0402091438.14018f5a%40posting.google.com BTW.: AFAIK it doesn't segfault, it exit()s. Any manufacturer is free to limit the use of his programs as he wants. I agree, this behavior isn't nice, but life isn't nice either (sometimes).
