Issue with errtrace

Hi all,

Recently upgraded to 3.2 and noticed some differences in a lot of my
scripts, consider the following example:

#!/bin/bash

trap error_reporter ERR
set -o errexit
set -o errtrace
set -o nounset
set -o pipefail
logf_error=/dev/null

function _exit
{
  local -ri retval="${1:-$?}"
  exit ${retval}
}

function error_reporter {
  local -ri retval=$?
  #echo "Error in script setup. Exiting with error value ${retval}."
  local -i i=0
  #echo "Function call stack:" >&2
  while caller $i >&2; do  (( i++ ));  done
  _exit ${retval}

}

function echo_aaaa {  #this is called as a $(command)

#a subcommand might return with 1 in the script, but in most cases it is
not a problem.
#At least in our scripts there are a lot of cases like this where the error
is handled afterwards
echo "aaaa" | grep b
echo "Execution continues"
}

echo "Turning off errtrace"
set +o errtrace
var=$(echo_aaaa)    #calling as a $(command)
echo $var
echo "Turning on errtrace"
set -o errtrace

echo "Next command will fail in bash3.2"
var=$(echo_aaaa)    #calling as a $(command)
echo $var



Doesnt work right on 3.2


Output from 3.0

address@hidden:/# /tmp/test
/tmp/test
Turning off errtrace
Execution continues
Turning on errtrace
Next command will fail in bash3.2
Execution continues
address@hidden:/# echo $BASH_VERSION
echo $BASH_VERSION
3.00.16(1)-release
address@hidden:/#


Output from 3.2

address@hidden:/# /tmp/test
Turning off errtrace
Execution continues
Turning on errtrace
Next command will fail in bash3.2
26 echo_aaaa /tmp/test
42 main /tmp/test
42 main /tmp/test
address@hidden:/# echo $BASH_VERSION
3.2.51(1)-release
address@hidden:/#



Could anyone point me in correct direction on this one ?

Regards
Dave
