dovecot.log:

lda(mail): Error: program `/home/mail/bin/notify.sh' terminated abnormally, signal 11

dmesg:

dovecot-lda[7814] general protection ip:7f72b8c99286 sp:7ffdeccca478 error:0 in libc-2.24.so[7f72b8c19000+195000]

Steps to reproduce

notify.sh:

#!/bin/sh

echo "$1"

.dovecot.sieve:

execute "notify.sh" [ "hello" ];

make it crash:

$ cat mail | dovecot-lda
