Issue found on Mantic since 6.5.0-11.11

Test failed with:
  running attach_disconnected
  Fatal Error (unix_fd_server): Unable to run test sub-executable

By hacking the tests/regression/apparmor/prologue.inc:
diff --git a/prologue.inc.orig b/prologue.inc
index 9da05f2..fafc244 100755
--- a/prologue.inc.orig
+++ b/prologue.inc

        # global _pfmode _known _testdesc outfile teststatus testname
        local ret expectedsig killedsig
+ echo "==== $outfile ==="
        ret=`cat $outfile 2>/dev/null`
+ echo "$ret"
        teststatus=pass

        case "$ret" in

Run tests/regression/apparmor/attach_disconnected.sh manually, you will find the test is failing because the test result got appended to the $outfile:

$ sudo bash attach_disconnected.sh
==== /tmp/sdtest.345049-12729-P0mta1/output.unix_fd_server ===
PASS
==== /tmp/sdtest.345049-12729-P0mta1/output.unix_fd_server ===
PASS
PASS
Fatal Error (unix_fd_server): Unable to run test sub-executable

And consequently falls in the case of testerror:
  *) testerror
          return
          ;;
