Hi,
I can't reproduce this so far. I followed your little recipe and nothing
adverse happens.
I also don't see how this could happen based on the code.
Is anyone else seeing this?
Regards,
Stephan.

Package: dovecot-sieve
Version: 1:2.2.18-1
Severity: normal
Dear Maintainer,
On my system, sieve-test segfaults on the following minified Sieve script:
require ["editheader"];
addheader "foo" "bar";
if header :is "foo" "baz" { }
To reproduce, put the above script in script.sieve and do the following:
echo > mail
cat > dovecot.conf <<EOF
plugin {
sieve_extensions = +editheader
}
EOF
sieve-test -c dovecot.conf script.sieve mail
The sieve-test command should segfault.
Here is a backtrace:

sieve-test used to work fine on the (non-minified) script on which it now
segfaults, so this bug was probably introduced by a recent version.
