MailScanner/SA crash (regex limit?)

[Julian Field]

I've just had a look at the latest code, and it should be relatively easy
to fix. All the code is there already, just it may stop when it encounters
a SpamAssassin problem (other than a timeout). There may be a log message
starting with "SpamAssassin failed with real error:". Did you get that log
message?

What version were you running?
What were the last things that MailScanner logged?

Is there any chance of a copy of the message that caused the error please?
I will obviously only use it for testing the code to get this problem
fixed, and I will keep it entirely confidential.

I've never been able to crash SpamAssassin in this way, making it a little
difficult to test!
