I was expecting Free Pascal not to have the bug, as Pascal generally fails with a visible runtime error, as it does I/O checking by default. However, it seems not to do it when WriteLn goes to the standard output... (even if it is then piped to /dev/full). So the basic begin WriteLn('Hello World!'); end. definitely has the bug, at least with the fpc implementation. On the other hand, explicitly trying to write to /dev/full from the Pascal source triggers a beautiful message: Runtime error 101 at $0000000000401104
