As Chris said, some error, because return is not in function.

Example:
f1() {
    : | while :; do return 3; done
    echo $?
    return 1
}
echo $?
f1; echo $?
return 2

Looks like the bash doesn't restore the i'm-in-function indicator when 
running compound command (like while or if) in functions' subshell.
