Hi rainbowsally,
There was nothing wrong with the function. If you look carefully, you'll find out that the line you added will actually never be called  There is no way the code evaluation could get out of the infinite for-loop, other than one of the first three return statements.
So even though some compilers might warn about missing return statement, there is actually no problem or undefined behavior in this function.
Best regards,
Honza
