Title:
  set -e reverses order of signal handlers

Status in dash:
  New
Status in dash package in Ubuntu:
  New

Bug description:
  When `-e` is not specified, an INT signal handler runs before an EXIT
  signal handler; when -e is specified, the EXIT signal handler is run
  (but only one of its statements) and then the INT signal handler is
  run.

  :;  /bin/dash < ./trap.sh 
  ^Ctrapped: SIG_
  trapped: EXIT 2
  next part
  :;  /bin/dash -e < ./trap.sh 
  ^Ctrapped: EXIT 130
  trapped: SIG_

  With `bash --posix` or `busybox sh`, the order of signal handlers is
  the same no matter whether `-e` is specified or no. Please see the
  attached script, `trap.sh`.
