As a practical matter, the message appears to be a warning in the log,
but the results would be correct, so it can be ignored.

I've open a bug in which I noted my suspicion of what is happening.

If you have a sanitized email that consistently causes this to happen,
please attach it to the bug report.
As I said in the bug report, I suspect that an email that does not pass
a DMARC chack, has one or more Authentication-Results headers, and none
of them have an spf= field, would result in this error.

Hello,
after updating SA 4.0.0 to 4.0.1, (CentOS 7 - Perl version 5.16.3) I get
the following message in log regarding the DMARC plugin:
plugin: eval failed: Can't use an undefined value as an ARRAY reference

File "DMARC.pm":

signature details
_ my @spf_parsed = sort { ( $a->{authres_parsed}{spf}{arc_index} // 0
) <=> ( $b->{authres_parsed}{spf}{arc_index} // 0 ) }
@{$pms->{authres_parsed}{spf}};_
my $old_arc_index = 0;
Any ideas how to solve it ?
Regards,
Mateusz
