I tried. The core is not that of cupsd but that of cups-browsed, and 
this did not crash but was killed by sigkill

Reading symbols from /usr/sbin/cups-browsed...(no debugging symbols 
found)...done.

Note that I forgot to check how old this file was, thus it was not 
necessarily relevant

Then I looked at the startup script of the service 
(/lib/svc/method/svc-cupsd) and this one starts gutenprint and then 
/usr/sbin/cupsd.

If I try to start cupsd manually, it works and does not stop. It prints  
the test page, although with a message "filter failed" on the cups web 
page. If configured for black and white, the printing is OK, in colors, 
the black is purple, but my printer is an old brother MFC9330-CDW 
emulating a hp printer. However, when I print from a windows machine, 
the colors are OK.

I had the color problem before, but the service did not crash: thus its 
probably anothe problem


Then I discovered that I had , in the svcs list, a legacy server 
"cups-browsed" surviving from an old release:

ls -l /usr/sbin/*cups*
-r-xr-xr-x 1 root bin  294664 nov.  18 12:57 /usr/sbin/cups-browsed*
-r-xr-xr-x 1 root bin   72696 nov.  18 12:56 /usr/sbin/cups-genppd.5.3*
-r-xr-xr-x 1 root bin   28835 févr. 10  2022 /usr/sbin/cups-genppdupdate*

-r-xr-xr-x 1 root bin   21184 janv.  3 12:13 /usr/sbin/cupsctl*
-r-xr-xr-x 1 root bin  592640 janv.  3 12:13 /usr/sbin/cupsd*
lrwxrwxrwx 1 root root     10 févr. 10  2022 /usr/sbin/cupsdisable -> 
cupsaccept*
lrwxrwxrwx 1 root root     10 févr. 10  2022 /usr/sbin/cupsenable -> 
cupsaccept*
-r-xr-xr-x 1 root bin   61688 janv.  3 12:13 /usr/sbin/cupsfilter*
lrwxrwxrwx 1 root root     10 févr. 10  2022 /usr/sbin/cupsreject -> 
cupsaccept*

removing the legacy service on /etc/rc3.d has apparently for result 
that, on reboot, the cups service is running, but it crashes as soon as 
I try to print something.

If restart cupsd manually (/usr/sbin/cupsd), it starts and prints the 
jobs remaining in the queue (all are marked :stopped filter failed)

There is apparently no new core file (I checked running "updatedb; 
locate -b '\core'|more")
The only difference between starting cupsd manually or as a service is 
that, as a sevice, the gutenprint command is run before starting cupsd
