This is not a bug. The `local' command successfully performs the variable assignment and its exit status reflects that.

The special case is a command consisting only of variable assignments, which returns as its exit status the status of the last command substitution.

I'm sorry if this is an inappropriate place to submit this bug.   The mailing list doesnt work for me.

This bash bug occurs in 5.0.17, 4.2.46 and 3.2.25:

-------------
#!/bin/bash

function f() {
   local f=$( false )
   local -i c=$?
   # $c is always incorrectly zero
   echo $c
}

function g() {
   local f
   f=$( false )
   local -i c=$?
   # $c is correctly set
   echo $c
}

f
g
-------------------

The unexpected output for me is:
------
brian@desktop:~$ ./a.sh
0
1
------
