Is this reproducible by submitting the same problematic message?
Better still, reproducible using a command line spamassassin?

A detailed log may narrow down the problem area. If the crash
occurs within SpamAssassin, that would be: $sa_debug=1;
along with $log_level 3 or more (preferably 5).

It seems the crash occurs while attempting to extend the
process' virtual memory (the _morecore). Could it be that the
swap space is too small? Or perhaps we are dealing with a
runaway regular expression.
