Seems like a bug in that shell.
#! lines are not typically interpreted by the shell. Behaviour between systems varies: POSIX leaves the results explicitly unspecified when you run a script that begins with these two characters. The Linux program loader expects to find a newline in the first 128 bytes of the file (increased to 256 in recent versions), otherwise you will get an ENOEXEC error from execve. Cheers, Nick
