Looks like return builtin falsely exit execution of while loop instead of

What would you like to see happen?  You're in a subshell: the function
can't return, since this is not the shell that called it.  Do you want
parent and child shells both continuing execution after the function call?


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

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.
