procmail 3.10 dumping core??

Hello,

I just upgraded my hub machine from sendmail Sun Version 5 to SMI-8.6. 
There seems to be some incompatibility between the new sendmail and
procmail 3.10. The machine is running Solaris 2.3 :-( 

I have seen numerous entries in 'mailq' that look like:

GAA21594      141 Thu Mar  6 06:00 jklein
                 (mailer prog died with signal 213)
                           "|IFS=' '&&exec /usr/local/bin/procmail -f- 2

I assume that signal 213 (Octal) is really 13 octal which is SEGSEGV(11).
There also seems to be a corresponding sendmail core dump in /var/spool/mqueue
which did die with a SEGV.

Below is one .procmailrc which is causing the errors. Before I
start playing around with verbose and debugging levels, I was wondering if
anybody has seen this before and can help me resolve this.

Thanks,
Joe Klein

Here is the .procmailrc file. (user & host names changed to protect the
innocent:-)).
