sa-update generates errors

[Eric Krona]

From time to time when sa-update is running, I get errors in the output.
Like today I got:
Illegal octal digit '8' ignored at 
/usr/share/perl5/Mail/SpamAssassin/Plugin/BodyRuleBaseExtractor.pm line 
1083, <$fh> line 1097.
re2c: error: line 170, column 2: unterminated string constant (missing ")
command 're2c -i -b -o scanner2.c scanner2.re' failed: exit 1

What is the reason for it, are some rules poorly written, or do I miss 
some library or what could be the problem?
