Segmentation fault bash 4.3.022

[lolilolicon]

Sorry for the unhelpful title, but I can't find a one that isn't
longer than the body of the mail.

The following code segfaults when run by bash 4.3.022

  set -E
  shopt -s lastpipe
  trap -- 'true' ERR
  true | { true | false; }

This is probably related to the bug patched by bash43-022.
