Trouble with procmail 3.11pre7

I'm having a serious issue with procmail 3.11pre7.  I've e-mailed the
author to no avail.

I have sendmail 8.8.7 under FreeBSD 2.2.2-RELEASE configured to use
procmail as the default local delivery agent.  Whenever sendmail
receives a large (over 1.5MB) file for local delivery and hands it off
to procmail, procmail attempts to allocate all available memory and
then dies with signal 11, leaving the mail in the queue to have
delivery attempted (and failed) later.  I'm assuming there's a memory
leak somewhere, but I have no idea how to find it.
 
If anyone else has esxperienced this issue, or knows of a fix, please
let me know.

Thanks,

--Michael
