OpenSMTPD 7.9 + filter-spamassassin terminating

Hello,

Today I updated two servers to OpenBSD 7.9.  The install process went 
smoothly, but post-upgrade filter-spamassassin terminates when it checks 
e-mail and then OpenSMTPD terminates.

In my smtpd.conf I have:

     filter check_SA proc-exec "filter-spamassassin localhost:783 
10485760" user _spamflt group _spamflt

When I send an inbound test message and it gets passed to smtpd I note 
the following log messages:

     Jun  5 20:23:08 new filter-spamassassin[74680]: 27cbbce50b3f9c39 
protocol report 0.8
     Jun  5 20:23:08 new filter-spamassassin[74680]: exit
     Jun  5 20:23:08 new smtpd[40878]: warn: lost processor: check_SA 
exited abnormally
     Jun  5 20:23:08 new smtpd[40878]: Exiting

In checking my logs pre-upgrade, I did not observe that line 
"...protocol report 0.8".  I have verified that SA is running and 
available via localhost:783.

For the time being, I have commented this filter out of my list of port 
25 filters.

Has anyone run into anything similar ?

Thanks in advance for any help,

- J
