Note that composing a multipart message with one or more message/rfc822 where the subtype is not explicitly specified does not segfault, due to the way this is handled by lib-client (2007). Test script: --------------- <?php $bodies = [[ 'type' => TYPEMULTIPART, ], [ 'type' => TYPETEXT, 'contents.data' => 'some text', ], [ 'type' => TYPEMESSAGE, 'subtype' => 'RFC822', ]]; imap_mail_compose([], $bodies); echo "done\n"; ?> Expected result: ---------------- done Actual result: -------------- segfault ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=80242&edit=1
