Sorry for the delay, but why do you think it's a bug? If you exec a command
and the command fails, it is normal for shell process to quit. (because `exec cmd`
replaces the shell with `cmd` and there is no place for `cmd` to return in your case)
See man pages of exec and zshall (it contains a list of reserved words) for detail.
If you have any other question, feel free to ask.
