stdio, for example, buffers more if the output device is not a tty.

If the program crashes or exits rudely, the buffers might not get

Buffering on a pipe might be less than on a file (I don't remember).

	/usr/bin/fantasdic -o Japanese 右 ; echo "return code $?" >&2
That might show if the exit was bad.

You can always use strace.
